20mb working fine until Friday then Sloooow
 

Anyone in the Sheffield area had a sudden slow down around 18:00 on 20 meg cable???

Normally I can download at 1200kb/sec to 1600 Kb/sec but now 400 max if I'm lucky. Straight into PC same thing thing so it isn't the router. Used Virgin media servers and ATI website as the download test as these are more reliable than speedtests.

I've switched the cable modem off for now and leave it overnight then re-connect and see what happens.

That's the beauty of having two broadband connections. I've got 8meg ukonline but it won't go higher and since I've got a dual lan router why not have load balancing and fall over protection. Hence 20 meg Virgin or at the moment very slow virgin.

UKonline is working at full speed. Virgin still slow this evening.

Post your modem config page 192.168.100.1
What modem do you have?
Have you rang tech support on 151 free (daytime as UK call centres are better)

Just phoned virgin media and there's a fault in my area which should fixed by July 3rd.

Pity it's not on the service status.

Just to add salt into the wound by mother supplier ukonline has got a fault on it's BT exchange and that's died a death. Engineer on site looking at it.

Re: 20mb working fimne until Friday then Sloooow
 

Even worse today 39k/sec from virgin media services. Time to call again.

rang again will still got a fault sir but your end is fine.

Won't be long until I'm getting angry. Back to ukonline for the time being.

Re: 20mb working fimne until Friday then Sloooow
 

Still very slow connection speed too tired to at the moment to ring them up.
However I'm not going to be so nice to thema s this has been three weeks when the 20 meg connection is really 2 meg or less.

Re: 20mb working fimne until Friday then Sloooow
 

Well rang up and they said still got a fault when I got a bit grumpy said they'll refund me for the last three weeks. Hard to argue with that.

Will they ever fix it though????

Re: 20mb working fimne until Friday then Sloooow
 

try the newsgroups i got good results there last few days

Re: 20mb working fimne until Friday then Sloooow
 

Will do if they don't fix it this week. At least I've got a time from the guy this time rather than I don't know.

Re: 20mb working fimne until Friday then Sloooow
 

Briefly had some decent speed this afternoon now back to slow again.

Re: 20mb working fimne until Friday then Sloooow

Re: 20mb working fimne until Friday then Sloooow
 

Well today for the first time seems to have decent speeds. Stopped me ringing up to complain again.
I'll check again tomorrow and see if it wasn't a one off.
