Smart Home, Software, Hardware, Mobile Computing & Co.Our reader Daniel recently pointed out how to get more performance in the network from a Synology NAS using SMB multichannel.Now he had given me a tip for you, albeit niche, which might help one or the other.So I'm happy to pass this on to our readers.DSL and fiber optic customers of MagentaZuhause can optionally book the “Failsafe via LTE” option from Telekom for €4.99 per month, which means that they can fall back on LTE in the event of a DSL/fiber optic fault.This can also work with an AVM FRITZ!Box.Since Telekom officially only offers this with a Speedport Pro (Plus), there is no guarantee that this will always work or that you will receive support for this type of use.Unfortunately, the telephony currently does not work on the Fritz!Box with an LTE fallback for several reasons, on the one hand because of the DNS query for the Telekom SIP server and on the other hand the Fritz!Box fallback does not support IPv6.However, you can simply use an LTE stick on an existing Fritz!Box, e.g.B. the 7490, 7530, 7590, etc. The advantage of the SIM card is that there is no volume limit as with the regular mobile phone tariffs.Owners of a 6890 can be happy because you can also use DSL and LTE there in parallel, and thus get a boost.However, it should be noted that this hybrid SIM card is not prioritized in mobile communications and is throttled in the case of a heavily loaded mobile network cell compared to a regular mobile network tariff.To set it up, you have to enter the APN nonbonding.hybrid in the Fritz!Box.A username or password does not have to be specified.After the connection you should get an IPv4 IP from the network 2.160.xx in the online monitor of the Fritz!Box.If IPv6 is supported, you get the "2003::" network as in the associated DSL/fiber optic connection.With the 6890, you only get IPv6 on the primary connection, not on the fallback connection.(Addendum: The best way to book fun is via the hotline or the "Telekom hilft" team on Twitter. Anyone who has booked a real hybrid can have the card switched to backup on the hotline, it works.This article contains affiliate links, so we're marking it as advertising.Clicking on it will take you directly to the provider.If you decide to make a purchase there, we will receive a small commission.Nothing changes in the price for you.Thank you for your support!Hi, thanks for the tip.Which stick or which tariff is suitable for this?It almost doesn't matter which LTE stick you use.tariff?It is an option for DSL/fiber optic connection.The stick is not without it, at least in my experience.The Huawei 8372 never worked for me on the 7530 (also AX) and the 7590 AX.Hello, I see that exactly like Lukas.It is far from “any” stick.It would be good if you shared your experience with which ones work and which don't.Greetings MarkusThanks for the tip!Only today, after several hours of DSL failure, toyed with the idea of ​​booking the option.I can save myself the Speedport Pro with the solution.Does anyone have experience with the option or the solution described above?Does the system switch reliably so that, in the best case scenario, there is no interruption at all?With the 6890 it works almost seamlessly, you wouldn't notice anything when surfing, games or voice chat could lead to a disconennct, but you would be reconnected immediately.I can also set up a mobile hotspot at home with my mobile phone if the DSL/landline network is disrupted.Most of the time, however, the mobile network is disrupted and not the Telekom landline / DSL network!It's all shit somehow.Fiber to the house would probably be best.Or be offline for a round?There are supposed to be people who long for a disruption in the network so that they can get a break and have to get out into real life.😉In many comments you can read that hybrid is not fully supported.A proprietary process that AVM has not implemented is used for Telekom Hybrid channel bundling.In the case of a stream, this means that the data packets cannot take different paths here.Then you didn't understand the article, that this is not about the proprietary tunnel where bundling is done.But then you can't use "Telekom Hybrid" with the Fritzbox either!Exactly the opposite of the title.Yes, there are regular hybrids with the boost option (APN hybrid.telekom), which doesn't work here, that's right, and there is the backup option (APN nonbonding.hybrid), where everything works without the tunnel.Then it is not the hybrid option, but only an emergency option.More precisely, the parallel operation is even more an abuse of the tariff and could lead to the termination of the contract!I also find it misleading.The “product” might be called hybrid, but technically it has nothing to do with hybrid…The APN includes the name Hybrid, the product is called Hybrid Backup, it just is.And technically, the card is linked to the connection, both from the location and from the IPv6 network, etc., and thus also to the well-known hybrid, which is called Hybrid Turbo.Are you sure that parallel operation is also possible with a 6590?It has no DSL modem at all.In addition, I can't find the setting for this (not even if the Internet is connected via WAN).The 6850 actually has no DSL, so of course it doesn't fit.I can't find the "Failsafe over LTE" option in my account...This option is best ordered via the hotline or Telekom Hilft, it cannot be booked online for existing customers.I was surprised, because I've never read anything about it, but I just checked again: neither in the contract options for my Telekon DSL contract (Magenta Home L) nor in the Telekom Hilft Forum can I find anything about an add-on option "Failsafe over LTE "Is that option still available?Yes, just look at the tariff selection for DSL/fiber optics, there is a check mark that you can tick.Booking directly currently only for new customers, otherwise just via the hotline/help team as an existing customer.Actually a great thing….but sadly didn't think it through..."Correct" fallback would be if, in the event of a DSL failure, the fixed DSL IP from the Business VDSL contract was assigned to the fallback mobile connection until the DSL connection worked again.Because then the RDNS entry would still "fit" and you could continue to operate internal mail servers without any problems.Such a service would be worth a surcharge for me - and certainly for many other smaller customers with their own mail server.I already have the necessary 6890LTE, the VDSL Business and the T-Mobile Business contract.But for decades Telekom hasn't managed to set up the various divisions in such a way that such real value-added products come out of it.Hello Arne, what you are looking for has another provider.But you can't get that for 5 euros either... Now you're in the business area with server operation, so playing around with the fries doesn't work.Greetings MarkusOf course, I also know that there are other providers who can do this.With my comment, I just wanted to address the deficits in Telekom's product policy.The currently only other major market player that offers both mobile communications and nationwide fixed network (from its own “production”) is out of the question for me as a supplier because of negative experiences from customer projects and its evil business practices.In my opinion, in Germany we currently have the choice between plague and cholera:Either serious and too lazy or agile but almost criminalI would be happy if Mr. Dommermuth could bring some movement into play.But strictly speaking, he lacks his own landline network.Hello Arne, well, if you only know two, then you haven't exhausted the market yet.There are more and there are good providers.But I won't mention the name here in the thread.Greetings MarkusIt would still be good if AVM made an entry in the knowledge database for this option, or adapted Doc 1612 for the 6890 LTE*.It's reproducible and well tested, it's been known for a year now that it works.Ask me why they pretend to be dead there and ignore the relevant information without comment...*https://avm.de/service/wissensbasis/dok/FRITZ-Box-6890-LTE/1612_FRITZ-Box-am-Hybrid-Anschluss-der-Telekom-einsetz/So it's not entirely clear to me.You have a landline connection for expensive money with Telekom, whether it's fiber optics or DSL and it's so reliable that you're willing to book a failure protection for 4.99 euros???The failure protection function in the Fritz!Box is nothing new and you can get an LTE stick for little money... But why not use a free solution for emergencies, which hopefully almost never occurs, e.g.B. a multi-SIM, which is part of the mobile phone contract, or a free SIM card with a few hundred MB from Netzclub, or somewhere else...A MultiSIM also costs money with Telekom, and if you have unlimited Internet for the same price of just under €5, you clearly have an advantage.With MultiSIM, you might need a day flat rate again, and a few hundred MB won’t get you very far, for example in the home office with zoom meetings, etc.But you should know about this topic https://www.ip-phone-forum.de/threads/telekom-hybrid-mit-fritzbox-oder-anderen-routern.312157/Well, not every multicard costs money, unless it's a Telekom contract... Kain already described it well in a comment below...The W1208 stick (4G Systems is the manufacturer), which is available cheaply as a 1&1 WLAN antenna, works quite well and if you have an o2 contract with a free multicard... well, you also have a failure protection that makes sense in the home office... Sure, a few hundred MB are not enough there...Yes exactly.€5 a month is an amount that I don't give a damn about if I get a useable fallback for it.Even if I only need it once or twice a year.I won't get very far with a few hundred MB from some windy free provider from Germany's worst mobile network.A contract with multi-SIM would either be more expensive than my current one plus the 5€ for hybrid backup or in a mobile network that was completely useless for me (and then again limited in data volume).If someone would like to use a stick with another box and also make calls via mobile radio via the Fritzbox, I can only recommend a used 1&1 antenna (stick w1208).Ideal for a multicard (especially if you were allowed to keep the o2Free option).If the primary internet goes down, you have a fallback.Also a mobile phone flat rate per election rule (if not included in the landline contract).The only disadvantage is that the stick switches to 2g for making calls.In a fallback situation, the Internet would of course be interrupted first, since telephony and Internet only work from 3G (4G now works for us).At Telekom you have a mobile phone flat rate included from the XL tariff at the latest, otherwise earlier if you are a Magenta1 customer.Sure you can do something like that with o2 SIM, but you don't have a public IP there, and a maximum of 10 Mbit, with Telekom significantly more depending on the load on the cell.I find the article interesting for users who have booked a Call & Surf connection S with Telekom, i.e. with 16 Mbit/s, because this is no longer possible.At least there was the hybrid option permanently free to book...If you can use the SIM card as described here, then you could go online via the stick and have faster internet with the Fritz!Box if the LTE network is not overloaded.It shouldn't work exactly for this one, since it's a regular hybrid with a tunnel, and the APN is blocked.It really only works with Hybrid Backup, and you get this in the new tariff.Whether there is something else possible, I can't say.That doesn't work really well with the fallback for the Fritz boxes anyway.I recently experimented with it.It seems that only if the DSL synchronization fails does the switch to the mobile network actually take place.In my case, only the Telekom account was unusable for a few days due to a tariff change.But since the synchronization with the DSLAM remained, the department did not make an automatic fallback, I could only activate it manually.However, what I found is that you can also use a Raspi Zero in OTG USB modem mode instead of the cellular modem.This allows other ways to be used as a fallback.I used my hotspot on my smartphone, for example, so I could connect the whole house to the Internet without an additional SIM.(But I also have quite decent reception and a data flat rate).To do this, you have to set up the Raspi as a WIFI client for the smartphone hotspot and at the same time as a gateway for the Fritzbox, and the Raspi itself must also act as a router.There are then just three routers connected in a row, but it works.Incidentally, it should also work to use a USB Ethernet adapter (with a specific chipset) if you have a LAN cable as a fallback upstream.There are at 7590 and co.extra to activate the extended reliability, which should step in for such cases as PPPoE errors, etc.In the 6890 you can, if necessary, also define DSL as a fallback with 2 or 3 clicks, or simply use both in parallel.Is the card location specific?Or could you simply put it as a second connection in, for example, a FB 6850 and "take it with you"?As far as I have read, this is localized in a kind of home zone.Should only serve as a replacement on site, not as an unlimited replacement for on the go.The article has several problems.Firstly, no hybrid is possible, as suggested in the title (which you should urgently correct). Secondly, the fallback option (at least in the business area) only contains a few 100 MB of traffic, every run-of-the-mill LTE SIM card can do that better.Thirdly, the fallback only works really well with LTE sticks that support the AT modem command set.But these days there are very few.This is a hybrid, also called the option "Hybrid Backup".There is no talk of business.It was tested by me with a 6890 and it can switch to LTE including fast.With LTE Stick, fallback has been possible for a long time.Years ago I installed and set up online cash registers for restaurants.I also find the headline misleading - no matter how many times the word "hybrid" appears somewhere.Every (involuntary) user of a Telekom hybrid tariff knows what it's all about - namely the bundling of DSL and LTE at the same time in order to get more speed.I also run the ugly chain: Telekom hybrid router + Fritzbox (7490) and was hoping with the help of this article to be able to take the Telekom device out of the equation - with the same result.Unfortunately, that's probably not possible.That should actually be rephrased.You can, something has already been written about it.Could one also act with 2 routers?Eg with Magenta Home S 16 MBit and the LTE option.I plug a Fritzbox for telephony into the telephone socket for the 16 MBit and I use the other Fritzbox with a USB LTE modem for the "300 MBit", even if most USB LTE modems only manage 150 MBit.Then I'm on the road with 2 WiFi networks but would use the WiFi of the Fritbox with the LTE for almost all devices.I only use the other Fritzbox with the 16 MBit for Telekom telephony and this WLAN only if LTE should fail.Would that scenario be possible or am I missing a technical catch here?Would be possible, you can also take a 6890, bundle both and say telephony from Telekom should only be done via DSL.You can also book the whole thing online as an existing customer, see: https://telekomhilft.telekom.de/t5/ Telefonie-Internet/Hybrid-LTE-buchen-neue-Hybrid-Option/ta-p/4700762No, it even says "As a backup/reliability: The Hybrid LTE Backup option cannot currently be booked online, but can be booked by telephone or in the Telekom Shop."Isn't the option "As turbo incl. backup" better than the pure backup, especially if you have a 6890 LTE that can do bundling!?If you find the option better, you also have to use the speed port, since the bundling runs over the proprietary tunnel, there is only one IP, no matter which way it goes.It must be the backup variant, this can also be used on 6890 for "bundling", here the FB distributes the whole thing randomly over both paths, and has different IP addresses.The LTE can be used regardless of the status of the DSL.It's more of a load sharing.Topic can quickly become confusing in detail.Can someone please help me out and explain what this sentence is all about?"However, it should be noted that this hybrid SIM card is not prioritized in mobile communications and is throttled in a heavily loaded mobile network cell compared to a regular mobile network tariff." I'm probably on the wrong here... if I understand that correctly, would that mean that every "regular" mobile phone tariff is prioritized, only the cards for the few hybrid connections that may exist have to be at the back when the bandwidth in the respective cell or your upstream is tight, right?Okay, thanks for the clarification, I wasn't aware of the difference 🙂 Do you know which way is more efficient?I think more of the one with the Speedport Hybrid, because of an IP and even packet distribution.The parts are available in the bay for less than €30, maybe ok for testing?In principle, I want 2 things: reliability (I also have night shifts in my home office) and an increase in bandwidth...Well, reliability in the home office, if you have good reception from O2 on 1800 and 2100 Mhz, you can see that in the AVM 6890, since all providers and frequencies are displayed to you there.Then you order the free O2 test card, which ends automatically after one month, but can only be ordered if you are not an O2 customer.Further repeat orders are possible, I'm sure I've already got the 10th 🙂 The 6890 bundles HYBRID TELEKOM SPH to the 6890 on the WAN connection with the free 02 test card.so my connection runs over slow DSL Telekom + LTE TELEKOM + O2 test card.More backbone and bundling 🙂Sparkassen-Card with Visa debit card as co-badge launchedMatter is ready: version 1.0 released, certification program startsUSB-C will be mandatory for mobile devices from 2024, these are the detailsTried Apple Watch Ultra: Apple is entering new territoryTelekom markets fiber optics in 27 new municipalities for more than 180,000 householdsTesla Vision is set to replace ultrasonic sensorsIkea Dirigera Hub listed in GermanyGoogle Pixel Watch official: This is Google's first smartwatchJames Bond films now available on Amazon Prime Video (but for a limited time)Top Four: Awesome Lock Screen App for iPhone 14 Pro (Max)Do you pay attention to energy efficiency when buying a device?We look forward to your tips, news & suggestions!To the formCaschy's Blog © 2022.
