Wifi hub keeps disappearing

[Tartancrusader]

My Vodafone Wifi hub keeps disappearing from my list of connections available and the only way I have found, so far, is to perform a hard reset on the router each time. I know it's not the PC that is at fault because it can see all of my neighbours' wifi hubs and it can also connect to my phone when it is hotspot-enabled. Yet at the same time, all my other devices can still connect to the Vodafone hub with no issues. I've tried to upgrade the hub's firmware but each time it fails.

Does anyone have any suggestions as to what is going on? 

Thanks very much.

(Edited to add: this is happening two or three times per day and there does not seem to be a pattern)

If you have an android device install "WiFi Analyzer" from the play store. When the router disappears grab a quick graph of the 2.4 Ghz band and post it here. It'll show whether it does actually disappear or just changed to channels your devices can't reach (most likely). In the case of unreachable you can get vodafone support to fix the router to a lower fixed channel.

Thank you, I will do that!

.@Ripshod Are you using an older version of the app? My one has square rather than rounded graphs for each detected device. My one is v3.0.10-62G(11-30).

@Cynric I may be using a totally different app to you. Mine says 3.11.2 (it's from farproc) 

To be honest either type of graph will show what we need to see.

.@Ripshod Fair point. What I was thinking about is that in your picture the spread of the signal shows a lot of overlap with adjacent channels. Anyway, this is going to drift a bit off topic if we start chatting about the merits of the different apps. 😁
