Wife's work laptop cutting router connection

[smarty156]

Sorry, meant I posted the Syslog earlier in this post when it was at it's worst (constantly disconnecting everyone). I think it's pretty clear from the log though that, as I mentioned earlier, everything actually remains connected to the router but the router is blocking any traffic through it either to other network devices (the NAS) or externally to the internet. The internet is also stable and remains connected the whole time. Seems to me it's an internal routing issue but I'm not technically minded, just going on the information to hand.

Thanks for trying to help but I've wasted hours of my life trying to get this working properly and not getting anywhere.
I've had enough and it's going back to Amazon for a refund. It's the second one I've had since October last year and the wireless signal is hopeless. I'm going to try a different make and see if that will just work out of the box like these things should.
