Hi

I have just had ADSL installed. I am finding that download speeds are
very slow (0.5 - 1k/s) much of the time, but sometimes jump up to
OK-ish levels. All the while, upload speeds are fine.

The BT engineer who came tested the line and got a download speed I
would have expected from my connection. He was using his own ADSL
modem, not the modem/router that I am using - a D-Link (not sure which
model, but it's a combined modem/wireless router).

I have tried different computers (with Windows XP, ME and NT4) but all
have the same problem.

Anyone got any ideas?

Thanks

Do you have a filter on the line between the wall socket and the
modem/router???

Are you using a wireless connection to your router?

Tried loads of websites, loads of different files - makes no difference

Something else is wrong.

No, but it sounds like I'm going through the same thing. It's driving
me nuts!!

What tends to happen is if I leave the line diconnected for several
hours, when I reconnect all is fine, d/l at full rate. After a shoirt
while though it gets slower and slower and grinds to a halt virtually.
Upload speed is fine! I've had BB a couple of months (I'm actually
with Openworld) and it used to be ok.

Tried both a Voyager USB and a Binatone ethernet router, tried
different PC's, Win98SE and Win2K, different filters, removed all
extension wiring etc, no help. Tried all sorts of RWIN and MTU
settings.

Sometimes, small downloads are OK (e.g. I can use google reasonably)
but downloading a file more than a few k is impossible.

BT tested the line, all OK (as I suspected, the SNR margin is good and
the modem never loses sync and reports few errors). Sent an engineer
out, he had no problems, they sent another engineer out and he sat
here surfing with his Win98 laptop and speedtouch "frog" for nearly an
hour with no probs. The minute I connect my gear, it all goes wrong
again.

Mine's been playing up since about the start of May, and is worse than
ever at the moment. Did the op ever find the fault? Please help, I'm
pulling my hair out over this one!!

what are you using now - MTU on the PC and if aplicable the router.

looks like an MTU problem. Get a command window (cmd in the Run box of
start) and try "ping www.bbc.co.uk -l 1472 -f' (the character befroe
the 1472 is a lowercase L)

if you get the response "Packet needs to be fragmented but DF set."
try 1430 instead of 1472, if that works you need the MTU at 1458. Same
if it times out.

so its either your gear or your ISP. What ISP and account type ?

Tried one, then the other then both. Every combination I could think
of!

Yep, did all that. That didn't fix it.

download a firmware upgrade for the ethernet router modem I was using
and the problem seems to be fixed on that, but the Voyager still has
the same problem. I'm happy cos I only needed the router to work, but
it still strikes me as odd that both of these modems suddenly
displayed the same problem yet worked fine in the past. I'm convinced
something must have changed with the exchange equipment, an upgrade or
something, that my modems couldn't cope with in their build state. If
I had the time to investigate, perhaps I would, but there's more
important things... :-)
