Windows 8.1 misbehaves with router?

[#1]

Hi
I might be completely wrong, but I'm wondering if a Windows 8.1 laptop is causing me problems with my PlusNet Thomson router.  The router is a TG585 v8, running firmware 8.2.7.8. 
Our network (Wifi and wired) and broadband have been working great for weeks.  We have Window 7 machines and smartphones (and a couple of NAS drives).  Then my daughter comes home from college, with her Windows 8.1 laptop, and suddenly we've had to do multiple reboots of the router this weekend to get the Wifi working and to reconnect to the internet.  Anyone shed any light?
Thanks in advance
Nick

The 585v8 had a long history of wireless problems, some of which were never really fixed.
I don't think it depends on Windows 7 or Windows 8.1, rather it depends on the manufacturer of the wireless card in the laptop. Anyway, some of the workarounds are given here:

Thanks for the steer.  I'll take a look.
Are there better routers PlusNet can supply?
