Given that you can see the WiFi connection this is now stranger. I assumed you couldn't even see it...

jcym advised trying a friends router and I second this advice. There's an alternative way if you have iPhone...
If you have an iPhone or a samsung galaxy you can do the following. Ensure you have 3G signal not Edge or GPRS...
On iPhone go to settings - personal hotspot - turn it on & if it asks to enable WiFi and bluetooth hotspot turn that on... and STAY ON THIS SCREEN. You should see the iPhone WiFi on another device now e.g. a laptop. Does this connect (it can take 60 seconds before it works)?

If it does then there's no reason the homehub wifi shouldn't work. It's using the same WiFi spectrum you see.
I personally just think the hub is faulty.

Turn this off now, it was just for a test

Have you tried changing the channel, try channel 1, then 6, then 11. If all of them fail I again feel it's a faulty hub. It's very very very unlikely that interference will create every non-overlapping channel to be unusable.

In reply to a post by clairej0:

I can see the hub listed on my mobile devices in the wifi.
But I cannot connect. I just get a notification that says unstable wifi and it disconnects

Hello. Were you able to try out greenglide's suggestion "You could try turning the security (in the router) off temporarily to see if that makes a difference"?

..... also you could switch off the Samsung devices & check if the others operate. then switch-on one by onestarting with tablet & lastly any S3's/S4's to see if there is any impact. this has been reported as a "design feature" on some forums wrt HH3 with loads of finger pointing between BT Retail & Samsung.

..... lastly re iPad password retention, the "Remember Network" flag in IOS 7 needs to be on for it to store network passwords (default is remember but it can get confused).
