Absolute top router, but caution in LTE telephony!

AVM FRITZ! Box 6840 LTE (LTE router, 300 Mbit / s, DECT base, 4 x Gigabit LAN) (Personal Computers)

Customer Review

With the AVM routers I've always been very satisfied for years. Many settings and freedoms which could not provide the "labeled" Provider router as Speedport and Easybox. So I looked to my LTE tariff (Vodafone) directly not disappointed the Fritz! Box 6840 and was worried until today. As well as already mentioned here, this router does not work with telecom LTE!

However, I do not use the LTE telephony and would therefore directly give an important clue to all those who intend to use this: On the one hand you have to extract from Vodafone with the appropriate tools, the voice password from the Easybox before use this function in the first place can. But the Internet offers for various instructions and technically somewhat interested users should be able to do this without any major problems, especially as some Internet forums can provide some guidance. But there is something else: As I gathered various LTE forums, some users have strong connection problems during telephone calls over LTE with the 6840th It is of frequent interruptions of telephone connection the speech. The company AVM is working but it and tries the problem with (beta) to get firmware updates in the handle. This information I did not want to share with you. However, it appears to affect only a subset of users.

Generally, an advantage for AVM routers is the fact that is just always worked actively in the firmware, so now were already a couple of 6840 out. Another important information: If you get a box with the first firmware, this may begin with externally connected external antenna is not much! But to my knowledge are likely to be the only the first revisions. Therefore, the information is important, because they allow companies (with external antenna) otherwise gets no proper connection and therefore can not! Update on the Fritz box surface. The Firmware Update You have to get so ahead of time and then play via computer.

The range of functions but as usual great in any case. Especially the latest firmware now includes things like MyFRITZ! (Manage the router via the Internet). Also you can use Fritz! NAS, this means that the Fritz! Box can be used as memory in the network, for example, if you connect a USB stick or an external hard drive to it. Thus, all computers on the network can access it. Without hard disk and USB stick has Fritz! Although NAS also has an internal memory, this falls to only 22 MB but very meager. Etc. For a couple of documents But is this also for fast data exchange.

Wi-Fi reception is with me very well, I was able to transmit power even testweise scale down to 6% and still got decent reception. The router is in my attic. Supports 2.4 GHz or 5 GHz, both at once but not (!) - Current Fritz boxes for DSL can do this. I use 2.4 GHz and I have especially delighted about the 300 Mbit WLAN. Although these 300 MBit course are only on paper. In practice, I can transfer data at 6-7 MB / s transfer (megabytes, not bits), which is already very good for WLAN. My old Speedport reached a maximum of 2 MB / s. In general, there are plenty of settings for WLAN. It be located in the area and displayed to the user even "disruptive" wireless transmitter. Nor can a WLAN guest access with private key set, which can be switched off after a predefined time on its own.

LAN can be found here as a Gigabit version, which will make an additional switch for most users probably unnecessary.

LTE Technically, there is more information than average Joe user needs in the surface. All kinds of data to link quality, RSRP, RSRQ, an alignment wizard to receive, reception history of the last 24 hours and much more. Alone for the handle to the Fritz! Box is already worth, because with the Easybox Vodafone can not nearly as precisely align the best reception you. And just this is just crucial for the achievable bandwidth in LTE. Just a few centimeters can have a great effect on the transmission performance. This was one of the many reasons why I have resorted to Friz! Box. While the Easybox when receiving only "red", "orange" and "green" knows, has the Fritz! Box alone in the "green" area of ​​Easybox thanks exact dates so many nuances that this is a difference of 10 Mbit to 20 Mbit can make bandwidth!

As a base station for DECT phones, the box can also be used, but this I have not been using, because I just do not use the telephone. Per Fritz! App but you can but even connect a smartphone to the router and phone calls about it.

Despite the currently partially occurring shortcomings in LTE telephony I can not give less than 5 stars this device because I do not use these functions. The possibilities are so numerous that I could name some of the most important here. And the most important thing for me: configurable or visible WLAN and LTE connections are very good, very stable and very detailed. The device makes here his job just great!
