yeah, I thought the auto selector on the shub just meant it defaulted to channel 6 instead of starting at channel 1.
Have you tried disabling 2.4ghz and using 5ghz only?
With regards to Pip's suggestion, I have got an app on my phone just for fun called wifi analyser which will do the same thing as what Pip is suggesting. You can see the signal strength from whatever device you are using to the access point, what channel you are currently connected on and the quality of the available channels so you know if you would be better off switching. The BT and VM access points are not mine and you should note that two of them are using channel 11 which is why I am assuming they have got a 0 rating and the app does not recommend using them.
