Does anyone have any idea what might be causing the issue? Is
tesco.net down or is my router playing up? The router is running
firmware V3.01.25.

On some occasions the connection lasts for hours.

Some further settings:

Multiplexing Method : VC-Based
VPI : 0
VCI : 38
Using WPA-PSK (Wi-Fi Protected Access Pre-Shared Key)
No firewall rules
MTU is 1458
Not setup to respond to ping on internet WAN port

ISP issue/Connection issue/line loss issue. Certainly nothing to do
with wireless.

When it's up, you might want to see what the downstream line loss is if
the router reports that. BT used to only support their 512kbps service
at something like -67dB and the 1 or 2Mbps service at something like -
53dB.

I used to run a 2Mbps service quite happily in the -40dB range though
and from what I could glean, the US folk run to much closer tolerances
than that. BT played very very safe in the beginning.

My numbers could be a bit off but that's the ballpark they were on. If
you can get that info then compare, if not then try an ADSL newsgroup.
