Infininty slowed to a crawl today ...

Hi all,

Hello, my Infinity has been great for most of the time since November.

Generally 37/8 megs on ethernet and 20/6 megs over wireless.

Today it's awful. Ethernet test showed download at 8 megs and upload at 7.97 megs on the BT tester.

IP Profile is still 38.71

The beta tester shows around 4-5 megs

Speedtest.net shows 4.05 megs up and 6.25 megs down.

And TBB is 3873 Kbps down and 4538 Kbps up

Any ideas? Absolutely nothing has changed here. This is silly.

Is there a problem out there in BT land, again?

Cheers,

Rob

OK

Re-booted the HH3 and all seems well again, just a slightly different IP dished out.

Rob

The IP Profile is calculated from sync speed.
Usually IP Profile is 96.79% of sync speed.

The problem is that quite often the HG612 modem can re-sync "on the fly".
These "on the fly" re-syncs do not always result in a new PPP session as they are too quick.
(around 16 seconds or so on my connection).

The way to force a new PPP session is to disconnect/reconnect the router or hub, or a full disconnect/reconnect of the modem (this second option is detected - sometimes negatively- by DLM at the cabinet DSLAM).

So if speeds appear low, yet the IP Profile is still high, a new PPP session will update the IP Profile accordingly.

It sounds like it could be the same issues as experienced by this person:

How can you tell that the modem has re-synced?

With an unlocked modem, the current sync rate can be seen in the modem's GUI, the ongoing graphs will show steps in the sync rate & connected time, the modem's internal log will show :-

2012-2-28 19:23:30 Notice 104500 DSL activate succeed
2012-2-28 19:23:14 Notice 104500 DSL deactivate

& the harvested data log(s) will show connected time in seconds & current sync speeds etc..........

With a locked modem, I suppose the first indication will be a change in achievable download/upload speeds.

Again, I think the only way to be sure with a locked modem is to disconnect/reconnect the router to obtain the true current IP Profile.

Rob,

Has this happened again since you last posted?

Only reason I ask is that after my initial teething problems with Infinity (which we've discussed in the past), my connection was running fine until I rebooted everything a few days ago. Ever since that reboot, I've found that the BT HH3 needs rebooting every day!

Each day I connect, speedtest shows 800k (!) download speed, and 1Mb upload. If I reboot the HH3, it's back up to 35Mb/6.5Mb, which is fine.

Just wondered if yours has settled down now? I've spoken to BT's Support in India yesterday and they are calling me back for a status update later today. Just seems strange that since I powered everything down a few days ago I now have to reboot the HH3 every day in order to get the performance back.

Anyone else faced this problem?

Cheers,

Nomadd

Hi

I have to re-boot the HH3 on a regular basis. My speed drops to 4-8 megs - a reboot generally cures it.

I just suspect that all the ISP's are trying to get their networks to work properly so they can use the iPlayers etc for the Olympics - not that I care much being up in the frozen North.And ... they are upsetting lots of bits of routing, which is notorious to isolate and then fix and then propagate out to all the other routers which need to know the new updated paths etc ...

Strange that lots of issues seem to be wth iPlayer and bbc site in general Or at least fast routes to the Beeb!

Call me suspicious -

Anyway, the bottom line seems to be, re-boot HH3 regularly -

Cheers,

Rob

Glad I didn't buy one of these.

We didn't. It came free with Infinity.

Still, you get what you pay for, eh?

I was lucky I think and got hh2 just before the change over. Then they offered hh3 for £50.

roflol HH2 has been consigned to the bin here as well!

My problems began when I actually rebooted the HH3!

After 3 days of it slowing to a crawl overnight, I finally did the "full factory reset" by sticking a pin in the hole in the back. It's been fine since.

Phew. Thought I'd have to get the engineers out again!

My HH3 was only used while the engineers were installing Infinity, as soon as they left it was replaced by my Airport Exreme Base Station. The HH3 is back in its box.

Oh well,

Restart time again ... down to 2.5 down and 4 up ....

Rob
Edit: simple disconnect + reconnect via hub and all is just fine,.

Have you raised it as a fault with BT?

Yes, raised as a fault - engineer been and spent hours checking everything - all just fine, from here to the cab, the cross link between cabs, and back to the exchange,

All just working as it should. And, when he left, 37.5down, 8 up.

From what I see this seems to be a problem with the HH3 - far too many people are reporting the exact same issue.

After a few days, speed drops to 3-8 megs ... up can stay pretty much at 6-7 megs.

Cured by not even restarting the box, just a disconnect followed by a reconnect

-------- - simples!

Rob

So is the fault closed or open?

If closed, closed as solved?

Closed as solved.

I guess all they can do is swap out the HH3 - but if all I'm doing is reconnecting to the internet, and getting a new IP address, then I'm not sure what a change of HH3 would do.

If I was having to re-boot it all the time, then that would be a different matter.

Rob

PS - I notice there's now an issue in Newcastle just posted up on the BT site. The area code for York is not listed - but my IP seems to think I am connected to Newcastle (given the shopping ads and google etc ...). So, could be something there affecting me.

Personally, I'd reopen that fault and get it escalated to 2nd line.

I was told that the escalation was to 2nd line ... whatever that means - care to explain please?

On http://community.bt.com/t5/BT-Infinity/bd-p/BTInfinity loads of people are reporting the same issue ... this makes me think it's a bit more deep seated than duff HH3's ...

I had OR spend the best part of a day 3 years ago sorting my line out when I could only get 135k-160k from Orange (via a BT off-net solution) - the BT DLM just barfed at my line. 51 db to the exchange, 8 db from cab to my house. DLM needed around 15db noise margin to be stable at around 0.5 meg. Switched to O2 with no DLM, and managed a good 3-4 megs, nm around 2.5db. Now FFTC'd and the modem syncs at the full rate - the connection doesn't drop, just the speed!

Rob

I think 2nd line are the guys who can actually change things, rather than just take the call or respond on the online chat. I don't think it's a duff HH3 as others have reported similar problems with other routers.

I'd be inclined to keep on at them to fix it, hopefully finding out exactly what happened.

Thanks,

Yes, there does seem to be a more generic network issue. Seems to crop up more with Infinity - but then, maybe the slow down is much more noticeable

eg going from 37.5 down to say around 4-7 megs is huge, but going from say 6.5 megs down to 4-5megs, is not such an issue, and may not be noticed!!!

It's wierd that getting a new IP just fixes it like magic. I can't think what might be happening ... very very odd going on.

Doesn't seem to matter where people are connected into the network either, people all over are seeing the same problems.

Are we seeing the various ISP's trying to re-engineer their networks so they can stream the Olympics reasonably???? Call me a sceptic ...
