Hola Matthias, muy buen dia, > Which channel you would suggest? That depends. On your environment, the neighbourhood of APs (and probably a lot of other radiating sources in your area as others have pointed out). If you only look at WiFi, however, channels 1, 5, 9, and 13 may be a good choice -- if you use 802.11g/n and no one else nearby is on 802.11b or n only ([1], [2], and assuming that you're in the EU). > Thanks for any hint what I could do. That is difficult but maybe you can tell the phone not to attempt to go up to bandwidths above a certain bandwidth, or tell the AP not to. That reduces throuhgput but may lead to more stable connections in a noisy or edge-case environment. Other than that, I'd also be pretty much out of ideas, sorry. Saludos, Peter.

Which channel you would suggest? The question has todo with one of the BQ E4.5 Ubuntu cellphones I have here in my family: It connects fine with *any* AP outside my house (in my company, public APs and even using my iPhone 8 as AP in personal hotspot mode). But it does not work with the AP in question. It connects, get an IP assigned but traffic to/from get stuck. Maybe some interference which affects only this device. It was not always this way, it started from one day to the other...
