The first couple of days using Nildram ADSL since getting back online a couple of weeks ago were a little dodgy because it would occasionally drop the connection for some unknown reason for five minutes at a time, a reboot seemed to help but this could just be a coincidence.
Because it was actually working before my activation date I put it down to not being fully "activated".
It has been stable until now though and I've always been able to Telnet into the router to forward ports etc.
Last night though, I played some Colin McCrae '04, checked my mail and went out for a couple of hours.
When I came back I had no connection at all, I couldn't even Telnet into the router.
No problem I thought, maybe a patch cable has come loose or something. Nope, wasn't that.
It was as if the router was just dropping all packets from my PC, it had the DSL link and the LAN light was flickering whenever I tried to access the net.
Also, I could see that the router still had access to the net due to the PPPoE/ACT light flashing sometimes (net background noise etc).
When I tried to right click on the LAN connection to the router and select Repair (I was trying anything by this point), it said "TCP/IP is not installed for this connection" but when I viewed the properties TCP/IP was still ticked, with the same settings I've used the whole time.
Suddenly, after much head scratching this morning it just suddenly worked again...
The only thing I have changed is my computer name and workgroup but up until last night it had the old one and was working fine?
Can anyone shed any light on why my router would just ignore packets sent from the PC on the internal network?
