Thomson ST585 v7 Dropping wireless connection

[#1]

over the last couple of weeks this has hapened a few times. The laptops in the house suddenly lose connection and when you try to reconnect windows reports the router is not responding. The kids run to me complaining but I am oblivious in my office as my wired connection is still working fine. It takes a reboot of the router or turn wireless off an on again to fix it. Any ideas? Is my router dying?
Thanks

I've had exactly the same and posted on Saturday about it, on Sat I had done more restarts than I care to remember eventually the router just hung I eventually managed to get it reset via the little pinhole.
Same as you I've had it a few times, wireless connections gone not  showing in the available connections, normally it comes good on a restart from the gateway although a couple of times I've had to " pull the plug " on it .
Saturday I was on the point of giving up thinking the router had totally died! My routers only about 3 months old so hopefully its not on its last legs  
Perhaps its a router s/w issue

I'm having the same issue too.
I've only had the router a week but it's happened three times already.
The wireless light on the router flashes about once a minute (on the rest of the time).
My signal meter on the laptop flashes the signal is available when the router flashes, but it's for less than a second.
The network shows up as available but my 'password is incorrect'.
Connecting via ethernet and resetting doesn't work.
Not sure what the little button on the front is for, but I pressed it anyway.
The only thing that works is to pull the plug.
It doesn't happen when I'm connected.
It's when I've been off for a while and come back to it.
Mine is TG585 v8, Software Release: 8.2.7.7
It isn't a major problem, just flippen annoying.

Probably not much comfort to you but I have a TG585v8 with Software Release 8.2.7.7 that has been connected for over 87 days, running both a wired and a wireless connection. Both have given no trouble.
