Hi guys,

Around a month or so ago I transferred my line over from TalkTalk (Fibre Medium) to BT (Infinity 1)

All was okay for the first couple of weeks on BT, however, my line has now started to drop out. It was previously very stable.

The only differences I can see are the upload (obviously) which was 2mbps and now syncs at around 7-8mbps, and the download which always synced at around 35mbps on TalkTalk and was synced at 36mbps on BT while it was stable - now, it syncs at around 38mbps.

The drops are usually occurring from the evening onwards though do sometimes happen during the day. DLM doesn't seem to be kicking in to stop this - I suspect the drops aren't numerous enough to wake it up.

Could it be caused by BT having me on a faster DLM profile than TalkTalk? I note on this page that BT are potentially using the Speed profile whilst TalkTalk use Standard.

I did mention this to BT on the phone, and on twitter - but they say that there is nothing they can do in regards to FTTC DLM remotely and have booked an engineer after replacing my HH5A with no luck.

Do you think I'm thinking along the right lines here? Is there anything I should say to the engineer when he arrives to prod him in this direction, if so? I don't think the issue will manifest while he is here as it will be during the day.

Line stats below.

6. Data rate:   8071 / 38274
7. Maximum data rate:   8071 / 41603
8. Noise margin:           5.6 / 6.7
9. Line attenuation:   28.1 / 25.4
10. Signal attenuation:   28.2 / 22.9

it's very likely the hh5, since it's known to do stuff like that on a regular basis.

[Wilt]

Hmm...I might give my old TT HG635 a go - but two of them? Only in the evenings/at night?

Looking at the logs the router itself isn't rebooting, just the connection is dropping.

[tommy45]

 without looking at the router logs, and modem stats it's difficult to know if these "Drops" are only  PPPOE session drops or the modem loosing sync with the dslam in the street cab
 in order to use both you would have to be able to put the TT device into bridge mode unless it has a EWAN port, and use the other device as router only, Both are Pants, best buy either a HG612 3B bt or modem from ebay  and use with the hh5 or buy a 3rd party AIO solution such as the billion 8800nl or the axl version, or if youwish to spend more there are other brands available like Fritzbox

Usually the same lines in the logs when it happens, eg:

Obviously the variables are always different.

in order to use both you would have to be able to put the TT device into bridge mode unless it has a EWAN port, and use the other device as router only, Both are Pants, best buy either a HG612 3B bt or modem from ebay  and use with the hh5 or buy a 3rd party AIO solution such as the billion 8800nl or the axl version, or if youwish to spend more there are other brands available like Fritzbox

Is the HG635 locked to TT? Edit: Ah, no I didn't mean use both at the same time - I meant is it likely two homehubs would be showing the same fault which seems fairly time-specific

I do have a HG612 from a previous installation but would rather go all-in-one if I can get it working properly

[Dray]

Your problem may be that when you switched, G.INP got turned off.

I'm assuming you're connected to a Huawei cabinet, so this could be all wrong.

As you have a Huawei, you can plug that in and connect the HH5A to that. The HG612 will support G.INP and it should come on. But with the HH5A on its own, it doesn't support G.INP.

[burakkucat]

Just a quick comment from me . . . The snippet from the BT HH5 log that you posted, above, is indicative of the "HH5 syndrome".    The modem remains in synchronism with the DSLAM but the PPPoE session is terminated and then re-established. 

[Wilt]

Looks like I need to dig out the HG612, then.

[rickyjamo]

The people advising you of the HH5 syndrome are most likely as sounds exactly like the issue I very recently managed to rid myself of.

Look on the underside of the hub, rectangular info sticker: 

Top left hand corner it probably says "Home Hub 5.0 - type B"

Ask for / or get a new "Home Hub 5.0 - type A"

Problem solved.  Haven't got the foggiest why it resolves or what the fault was but it solved it immediately.

[Dray]

He has a Type A already.

[rickyjamo]

Ok, I'd have suggested the other way around had I known,

"Home Hub 5.0 - type A"  swap for the type B. Worth a shot if your ISP is BT, they send the hub within a few days and easy to swap over.  Costs nothing.

[Dray]

Except you can't choose which one they send you and there are more Type A's than Type B's. While the HH5B should be better on a Huawei cab, the wireless throughput is worse than the HH5A which is why I suggested a Huawei HG612 v3B to give the best of both worlds.

[tommy45]

ISP supplied modem/router leave a lot to be desired, best avoided

[Wilt]

So the engineer came and just fitted a mk3 faceplate to the master socket - but my connection also begun to sync lower (between 33-35mbps) very early that morning - the hub now seems to be staying connected.

I do, however, apparently have a hh5b on it's way out to me, so we will see how that goes (though I fully expect a hh5a to be in the box) - will be able to play with various setups to see which works best for me.

I know ISP provided kit isn't the best but once it is working it is 'good enough' for my purposes - not really interested in squeezing out every kb - just reasonable speed and reliability. Once that is sorted no router can be better value than 'free'.

Cheers for all your input guys.
