IP address issue

Archived from groups: microsoft.public.windows.networking.wireless (More info?)

I have just bought a Netgear WG614 router with a Netgear WG511. My OS is
WinXP Home SP2.

I am having problems connecting. Sometimes I connect and it can be online
for hours. Other times it keeps cutting out and the only way I can get
back on is to unplug the router for a minute and put it back on. I get
various error messages including:
Limited resources...the network did not assign a network address...
Could not renew IP address

Sometimes it logs on but there is no traffic at all, sometimes I cannot
even log on even though I can see the network when I go to View Available
Wireless Networks

Sorry if I am not including enough details but I am new to this and have
tried to read through the manual and troubleshoot but have found it very
confusing.

My router settings are...
Internet IP Address: get dynamically from ISP
DNS Address: get automaticaly from ISP
Router MAC Address: use default address

I use NTL cable broadband.
