|Thanks all -|
thanks Curt, I haven't had time to download and run through your troubleshooting doc but I will, that's very helpful.
Latest firmware, hmmm, it was working before and it won't have suddenly downgraded itself so I doubt that's the problem. Not impossible but very unlikely. Something's changed - the question is what?
Get a free router... I doubt my ISP will be so generous, not before they've wasted a lot of my time sending me down blind alleys that are chiefly designed to fob me off. Their tech support is trained to do that. I know because I've been down that road with previous problems. I also know that changing the router is not a definitve test - although it is worth trying. But first I'd like to try to understand what the problem is, if I can, before I throw that particular sledgehammer at it.
There are not many other wifi networks in range and not much stray radiation in the band either, not here.
Since I first wrote -
I have logged onto the router and it claims to be talking to the PC and to the ADSL at normal speeds, even when I can clearly see that it's gone down. Which is a bit bizarre. I can see the stats updating and I'm inclined to believe them up to a point: when there's no real traffic going on, how can it claim to be talking at about 6500 kb/s to the ADSL? There's no traffic to speak of, what's it measuring? I suppose there's a bit of handshaking going on. Anyway, I can do various things and the only action that seems to clear it is to reboot the router. I'm trying to find out whether the dynamic IP is getting reallocated. It looks unchanged, but is the ISP changing it and my router failing to accept the new address? Hard to know, all I can go by is what's displayed, which may be wrong.
Another test I will try is to log on using another PC. I have a couple of laptops I can bring home and see whether they all fail at once.
I'll keep nagging this one, it won't go away on its own...
