I want to be contacted by AndzejJ from the old forum.
He was helping me with a wifiproblem on a Rut241. Then the old forum was shut down.
He knows all the details on my case, so I really want him to contact me
Hi MikaelJ,
Apologies for the late reply.
Since the access to the old forum is lost, could you please remind me about the current situation with the WiFi?
Kind Regards,
Hi. Sorry about the old forum.
Iām the one with a Rut241, having problem with wifi sometimes disconnect internet only on my tablet but all other devices working perfect.
Because the old forum is gone I will do a quick reminder about the problem.
When I run all my other devices on the network itās no problems at all. But when I connect my tablet, sometimes the wifi become connected but no internet. And if other devices are connected when this occurs, the same happens with them. Sometimes it reconnect internet by it self, sometimes by switching wifi on/off on tablet, sometimes it says ācouldnāt connect because of authentication problemā and i have to reboot router by power of.
You couldnāt see any problems in the troubleshootfiles. Iāve tried a lot of different settings. I had the same problem with another tablet, but both works perfect with another router or with my phone hotspot. Iāve tried a simcard with another mobile operator, that didnāt solve the problem.
The tablet has been for service 3 times but they donāt find anything wrong, tablet works fine when theyāre testing.
In the last message in the old forum you said that I should try different encryptions for wifi, did that, even tried with no encryption at all, that didnāt solved it either.
But I have some new information. Iāve noticed something strange. The tablet are android (12). YouTube is already installed in the tablet from the beginning, and the problem never occurs when I streaming YouTube. It occurs when updating Google play apps. Or for example streaming Netflix, intalled from Google play. I did disable Google play protect to see if there was any difference, but no.
Any ideas about this?
Another thing Iāve been thinking about. Could it be something in the firewall in the router that causing problems?
To clarify. Iām starting to suspect that thereās something weird in the communication between android 12 Google play and the router.
Iāve borrowed a tablet with older android (9) and that worked perfect. My phone is android 11 and my TV also older android version, and they have no problems when connected.
The other tablet i had and my current are android 12, both had problems when connected to the Rut241, but not other networks.
One more thing Iāve noticed is that when i updating Google play apps or using apps installed from Play store, like Netflix and are connected to the router internet speed is slow. But with YouTube itās fine again.
When i connect my phone to the router and updating Play store apps the speed is fast. Also when I connect tablet to phone hotspot and updating Play store speed is fast.
I know this sounds weird, but this is whatās happening.
Hello,
If you havenāt made any changes to the Firewall settings, everything should be working fine. It is difficult to determine the exact cause of this specific issue, since it occurs only with a specific device when it is using specific applications.
Have you tried using an older firmware version like 7.02.7? You can download a backup file, downgrade via the bootloader, and check if the connection becomes more stable with the older firmware.
I assume you have tried different settings on the wireless interface, like increasing the DTIM interval.
To gather additional debugging information for your Wi-Fi, you can execute the following commands through the CLI and view the logs:
- uci set wireless.radio0.log_level=1
- uci commit
- wifi up | logread -f
The logs should provide more details. If you decide to share these logs, remember to blur any sensitive information for privacy reasons.
You may try lowering the MTU on the mobile interface, though I do not think that this will help.
Also, there should be a decent amount of general WiFi fixes in the v7.5 version for RUT241. I would recommend updating whenever v7.5 releases to check if the new firmware resolves this issue.
Kind Regards,
Hi
I have experimenting with different settings in the firewall, but after that Iāve done a factory reset, to ensure settings are at default. Yes Iāve tried different settings in wireless, and MTU in mobile.
I have tried every firmware version since the first one. The seller of my Rut241 send me another router to see if mine was broken, but the new had the same issue.
Iāve tried a simcard with another operator.
I live on the countryside, with only one neighbour. So the chances of interference from other networks are at minimum (Iāve tried different channels).
Like I said the problem only occurs with two tablets, both android 12, but different brands (Samsung and Acer). Both tablets works fine with other routers and networks.
All my other devices works perfect with my Rut241.
This problem is so mysterious and itās making me crazy, I have had this problem since I bought the router 6 months ago. If I havenāt been so stubborn Iāve given up a long time ago.
Well I will be waiting for the new firmware update and hope the problem is gone.
Hi again.
I found a hidden wifi developer options mode on my tablet.
Where you for example can find wifi and network information, and perform diagnostics. Diagnostics looks fine when Iām connected.
There where also router specific history. I can see a lot of disconnections and reconnections, like I experience. New and interesting information was that sometimes the disconnections only lasted for a few seconds, these disconnections isnāt noticeable when using tablet. But maybe that can be the explanation to why internet is slow on the tablet, but not on other devices.
In the history log I also noticed that sometimes when the tablet tries to reconnect it says:
DISCONNECTED
TRY_TO_CONNECT
ASSOC_REJECT
TRY_TO_CONNECT
DHCP
CONNECTED
Or this:
DISCONNECTED
TRY_TO_CONNECT
L2_CONNECT_FAIL
TRY_TO_CONNECT
DHCP
CONNECTED
What does it mean, ASSOC_REJECT and L2_CONNECT_FAIL?
Then i connected the tablet to my phone hotspot network. And of course there where no disconnections at all in the history log. Tablet works perfect with my phone hotspot or other networks Iāve tried. Also service shop didnāt find anything wrong when testing it.
Do you know when the new firmware version will be released?
Hello,
It appears that your tablet is experiencing various WiFi errors, like failed authentication/association and L2 errors, despite not changing the passphrase and trying different authentication methods. These issues might suggest a compatibility problem at a lower L2 layer between the two devices.
I assume your tablet is running the latest Andoid version available for your device?
As of now, the release date for v7.5 is uncertain. The original planned release date was postponed, and several fixes and features were included in v7.4.4 instead. However, the WiFi improvements for RUT241 should be included with v7.5.
Kind Regards,
Hi
Is there anything to do in settings to fix this?
Yes the tablet is updated.
Iāve had the same problems with two different android 12 tablets now, itās so strange that no one else experience same problem.
Iāll wait for v7.5. and keep you informed.
Thanks for the help

Hello,
Could you check if watching the videos on a lower quality still results in the same behavior? Try with 240p, 480p, 720p and so on.
Best regards,
Are you asking me or āmittererrā?
Hello,
When the issue occurs again, could you please run the following commands from the command line and share the output?
iwinfo wlan0 scan
iwinfo wlan0 assoclist
iwinfo wlan0-1 assoclist
dmesg
Before sharing the results of the scan, make sure to hide any sensitive details like MAC addresses.
Kind Regards,
Hi
Iām sorry, I donāt understand how to do that.
Could you explain?
Hello,
Those commands need to be executed from the command line on the device. We have instructions on how to access the command line here. For example, on Windows, you can download PuTTY to SSH to the device and access the command line. When accessing the command line, please enter ārootā as the username. The password will be the same as the one you use for WebUI access (the password is not visible when you enter it, but it is actually there).
Please, execute these commands after the issue occurs.
Kind Regards,
I couldnāt login to CLI.
When I go to CLI, there is only RUT241 login, but nowhere to type password.
I type root as login and then press enter, but nothing happens.
I donāt have any computer, only android tablet. Do you need a computer to login to CLI?
Hello,
When you enter ārootā as the login and press enter, you should be prompted to enter a passoword. Enter ārootā ā press enter ā type password ā press enter again.
Kind Regards,
Hi.
I canāt login. I type root and press enter, nothing happens. No text password appears.
Iāve tried to type the password and press enter anyway, but that doesnāt work.
Iāve tried with both my phone and tablet.
