The "AUTO" channel setting for the 2.4GHz band resets itself after a while (I suspect after the first channel hop occurs, as per the log).
The router's info is:
After setting the Channel to auto as below:
all looks fine, and devices are able to connect for a while. After a couple of minutes this shows up in the logs:
And now the configuration page looks like the channel has been manually set to 1:
I've done it a couple of times and it's easily reproducible, soon after setting it back to 'auto' it reverts to some random channel and stays there regardless of the channel's quality resulting in all the 802.1g equipment around the house not able to connect.
This makes the device unfit for purpuse as a WiFi router in residential areas. When can we expect a fix.
I can't say I have seen this before, however, you cannot rely on the System Log - that has bugs in it. I am currently testing & will get back to you.
You say this happens after only a couple of minutes. I have been testing so far for over 20 mins & although the channel has changed due to hopping, it still remains set to Auto. I have raised this with @OCE_Karl to check your line's configuration within TalkTalk's management system. Currently, he is checking this out for you.
I did say that you cannot rely on the system log,, there are numerous bugs in it. TalkTalk have made changes to your account to give you the control of your router that you want.
You should have full control of the router's channel allocation since that work was done.
You will need to ask TalkTalk about the changes made to your line, I am just a customer, therefore I have no visibility of the line configuration.
Optimisation has been turned off on your line temporarily while testing so that no remote changes are made to your wifi services such as promoting band switching between devices or optimising the channel based on interference patterns.
Your wifi will remain on a channel that you set manually.
