Disconnecting from the network for brief periods

Hi, im currently connected to a network I have no control over, and have been getting disconnected every 15 mins or so, I reconnect about 15 seconds later.

Untill one of their technicians come to look at it which could be up to 2 weeks is their any way i can test if it's my machine with the problem? (I have no spare machine)

 

Is there a way i can test my network cards at all because when it disconnects i get a 'limited connectivity' message appear and when i click resolve problem it says there may be an issue with my network adapter.

 

Ok now i got a different 'error' When it disconnected and reconnected itself it got onto the network but not the internet, when i clicked diagnose it said
'Cannot communicate with the promary DNS server'

solution: reset your network adapter local area connection 2, when i reset it it worked fine again, i have no idea what is going on here :confused

 

If it's a DNS problem, try checking the settings in your router for DNS server and use the DNS server for your own ISP (cable/ADSL company) or set your PC or router to use OpenDNS (208.67.222.222 and 208.67.220.220).

It might just be that your router is being buggy, restart it.
