Huge intermittent peak time packet loss

Anyone on ADSL2+ having trouble at peak time ~ (18:00-02:00) I know theres prioritisation trouble happening but lately I haven't been able to even browse websites or get email.
I've also noticed that my upstream sync has become stuck on 440kbps. Usualy it fluctuated around 800+
Are there any other problems plusnet are having which haven't been reported which sound like mine?

Re: Huge intermittent peak time packet loss

I have the same problem, between 6 and 2 it's so intermittent, it can be fine for 10 minute then absolute rubbish. Pages take forever to load, often have to be loaded several times, and to make matters worse I keep getting a really rubbish ping for my gaming, I'm tempted to move from Plusnet to Virgin if it doesn't improve soon. Odd thing is it started when the 21CN upgrade in my area did, improved for a few days after and its now back to being rubbish again.

Re: Huge intermittent peak time packet loss

Mines not great either since moving to ADSL2+ ... sometimes gaming i can get really bad lag... although downloading seems fine most of the time
Think ill stick it out because on the status pages it says there is a problem and they are looking to the vendors of the routers for a fix

Re: Huge intermittent peak time packet loss

I've also experienced my upstream getting stuck at 440 (443 in my case, if I remember correctly) for no apparent reason, when it was normally around 800. You could check with Plusnet to make sure they haven't put on any restrictions, but if that's not the case you might just have to wait. My upstream speed went up to 665 after about a fortnight, then returned to its normal 800+ range a couple of weeks later.

Re: Huge intermittent peak time packet loss

Still the same, frankly I'm getting sick of it, no update on when this will be resolved, almost a month now its been like this. If it doesn't get any better soon I'll just pay the money and move to Virgin.

Re: Huge intermittent peak time packet loss

I've also been getting this for about a month now and it's driving me insane: I am currently paying for a service that I can all but guarantee I won't be able to use most nights. Gateway hopping doesn't work; I can successfully ping and traceroute through to servers but cannot get any web traffic, email or anything else. It seems to be a problem with the gateways, as the packet loss (around 30%) from pings is the same to the gateway as it is to further out on the network.
Here are some traceroute logs from last night:

I raised a ticket but was told that PN can't find any faults and that I might be charged £170 if they raise it with BT  Angry

Re: Huge intermittent peak time packet loss

Still the same for me. Have switched routers and microfilters, connected to master socket, still no change. As far as my router is concerned I am connected. A quiet line test brings up nothing. Sending a ticket off now.

Re: Huge intermittent peak time packet loss

Bojangles, if you're at your computer now could you try pinging the gateway and posting up what you find? I have a theory but am not at home to test....

Re: Huge intermittent peak time packet loss

Ah, of course, I forgot that it's intermittent  Smiley
Assuming it goes at some point tonight, try measuring the ping results with different size packets (specifically, try 8 bytes, 16 bytes, 64 bytes, 128 bytes, 256 bytes and 512 bytes). I'll do the same.

Re: Huge intermittent peak time packet loss

YAY! Another night of dial-up style broadband, I think what I'm going to do is just write letters to all the websites I normally visit asking if they can write back with all the news and information since it would be faster and more convienient for me.

Mine's a beat-up old BT Voyager 2100. Convinced it's not the problem, though.
Interestingly my connection stayed fine all last night...

Re: Huge intermittent peak time packet loss

Bojangles: Having same peak time probs as you. Mine start around 15.00, and only since upgrading to ADSL2+ a couple of weeks ago. Download speeds 90kbps! Non peak:6500+ kbps.
I'm in contact with PN about it.

Re: Huge intermittent peak time packet loss

Mine was strangely fine last night. Starting to think it might be something to do with outside interference, we've also had trouble with our central heating control system not being able to communicate with the boiler.
Primary router is a Draytek Vigor 2800V, have also used a Netgear DG834.
