Awful speeds today - drop from 7.25Mbit to 0.7Mbit!

netgem21 · Oct 23, 2009, 18:54:04

Hi

Just been doing some speed tests and these are the results I've been constantly getting over the past week:

As you can see in my signature, my internet speeds are usually great. I have dis/reconnected, restarted the router, tested over wired and wireless, unplugged the phoneline - everything I can think of.

I'm on the DSL4 pipe - is there an outage at the moment?

Thanks in advance

A BT Speedtest would be useful, so we can see your profile. Not being funny, but if you've had this issue all week, it's a shame that you've left it until support are closed for the weekend to report it, as they could have checked out your line.

Are the low speeds consistent, or are they different at different times of the day?

Not sure what I can do about that - I tried to, and the browser crashed. Now it says I need to wait 3 hours.

I've been pretty busy this week, so I haven't had the chance to troubleshoot the issue myself, which I try to do beforehand!

Simon · Oct 23, 2009, 20:48:31

Understood.

The BT Tester is fickle at the best of times, but it usually only does the 3 hour thing after a successful test. Might be worth trying again in a bit. If it's been going on for several days, it sounds possible that it could be a line fault, but I'm only guessing, in the absence of anyone more knowledgeable. Sorry if we're not being much help.

Actually, I can tell you that my profile is not interleaved (8128)

Hey, don't worry - I understand it's not exactly the best time!

It's been going on since Wednesday night, I think.

Usually, my connection's pretty good, although I can't say the same for my wireless!!

I'll give it another go when it comes up.

Well, it may have been, but it could have dropped, of course.

Yeah, suppose - but it says 8128 in the router login page - isn't that live data?

Simon · Oct 23, 2009, 21:00:46

That's the sync rate, I think, not the profile. The only thing that reveals the profile, is the BT Speedtest, unfortunately.

If this a wireless connection can you try wired? If you've a spare router/gateway try that.

Yeah, I did a few times - it's exactly the same on both wired and wireless.

Lance · Oct 23, 2009, 22:26:21

Simon, you're doing well on this techy stuff!

Netgem - Without the BT speedtest, we can't establish your profile which could be what is limiting your speed. However, if you've had it all week I'm guessing it's not your profile as it would have gone back up by now. Indeed, with a sync of 8128 (which could be interleaved but that won't effect it) any change in profile from the sort of speed you actually have should happen within a day.

My first suggestion would have been as per steve's above. My second (purely because support are closed) is to try a different router if possible. The final thing is to report it to support via email or phone message as Simon could well be right in that it may be a line or exchange fault.

I've tested it both on wired and wireless and I'm getting the same result. I've also definitely got interleaving off, as I deactivated it. Sadly, I haven't got a second router.

I'm kinda hoping it'll just fix itself - everything seems fine my end, so it looks like an external issue.

Thanks to everyone in this thread for helping me out!

netgem21 · Oct 23, 2009, 22:41:31

I think it's recovering - the ping is at least back to normal, speed is still slower than usual:

Baz · Oct 24, 2009, 08:22:58

back to normal, infact this is better for me.must be a record...if you can trust these speed testers that is

just a glitch somewhere

just to prove a point this is from another tester

nice upload speed
