Model: M7350
Hardware Version: V6
Firmware Version: 6.2.2 Build 200821 Rel.1004n

Hi,

 

I'm using M7350 since a couple of weeks now and I can't get my devices to use it without being disconnected every 5 minutes sometimes. It's like short disconnections (about a couple of seconds each) where nothing is available even the router's management page is not accessible (http://tplinkmifi.net/).

 

Each time I'm losing connection I've such kind of entires in the M7350 system log:

 

 

What does "Current channel is not save, restart Wlan to avoid" mean exactly ?

It looks like M7350 keeps switching from a channel to another over and over again which make connexions unstable.

 

By the way I tried to force the channel number in settings but no matter what, when I get back to the  "Wireless Basic Settings" section I see errors like :

Wi-Fi channel has switched to 11 to avoid interference between Wi-Fi and LTE.

 

So how I can stop M7350 to switch channels over and over again and force it to a specific number ?

 

Thank you

@jails and All,

Thank you very much for your feedback.

For the issue mentioned here “ the change of wireless channel caused the disconnection of 4G signal”, the following firmware versions are available to improve this issue.

M7200(EU) v2 20200714
M7200(EU) v3 the latest official firmware-M7200(EU)_V3_211117 and above
M7350(EU) v5 20201019

Yesterday I tried to force the channel number to 11 since it was the only one who didn't end up to a warning message in "Wireless Basic Settings".

But no matter what this morning M7350 switched to the channel 7

Wi-Fi channel has switched to 7 to avoid interference between Wi-Fi and LTE.

 

I'm living in an apartment with a lot of Wifi networks available around (about 15) so this policy of switching channels automatically when interferences are detected, even when we explicitly force for a specific channel number, make my M7350 kinda useless.

 

By the way, when I set my android phone as Wifi Hotspot, there's no channel option but it's working and connections are stable.

Hi @TP-Link, thank you for keeping me updated on this issue.

Indeed I've another 4G LTE modem (which is working great with the same SIM card by the way) so I can wait.

Do you think it's more a matter of weeks or a matter of months for the beta firmware going out ?

Hi, I just got the firmware and sent it via private message.

Please let me know whether it worked or not.

Thank you.

  @jails 

hello,

my M7200 rev3 shows the same phenomenon. Firmware is up to date.  I was not able to correct the errors, same strategy as yours - my "solution" is: I use the 7200 as plain modem connected to an old AVM FritzBox (USB-tethering). Client devices then connect to the Fritz Router via cable or wlan. Works fine ;-)

Hi, what is the model number of your TP-Link device?

Can you check whether your device is included in the recommended solution above?

Thank you.
