Hi

Flashed my 8800AXL today and to my surprise lost nearly 3 mbs of speed !!
It went 68.86 down to 66.1mbs not what I wanted to see.
Nothing else had changed and my line is a very stable connection on New cab installed 3 weeks ago and I am the only one one it.
In fact I am the only one on 5 miles of new BT back bone to main exchange, so not problems with congestion!.

Put Home hub 5 back on and went back to 68.8mbs

Factory reset router and made no difference and reflashed.

So will give it a day if not will have to go back to old firmware, bit disappointed that its going down and not up or even staying the same.

Just to add my Home Hub 5 is the much sort after B model using a Bbroadcom chip set and its a Huawei Cab 800m from me

So should be no difference in speed, I would have thought the Billion should have been better if anything?

Phillip

Planning on upgrading my 8800axl to the new firmware as well. I did notice a speed improvement when moving from a 7800N + BT VHDSL modem to an 8800axl with integrated modem, so I hope I don't see a drop too. I bought this because Billion has been great, and this model uses the Broadcom chipset, which is just about the best out there. I'll report back when I've done the update.

Let us know how you get on with the older firmware

Hi Billion Fan

Ok put old firmware back on and it dropped even lower 65mb,I did a restore to get all my old setting back not sure if that is causing and issue.
put on Hub 5 B and now back to 67Mb

I will leave BT hub 5 on for a few days and see if the dlm recovers, think all the reboots is dropping the speed, not sure why the billion is slower ?
Once that has been on for a while I will do a flash to new firmware but not restore setting and see if that makes any difference.
Any idea why the billion is slower than the Hub 5 as they both use Broadcom chip sets?.

I have dslstats running 24/7 for last couple of weeks if you should need them.


So not sure why BT Hub 5 is beating Billion hands down

Also saw some strange dips on the new firmware on up load did the test 3 or 4 times and same on all of them

It does seem like DLM is kicking in, but I haven't seen any others with slower speeds when using the 8880 series compared with the Bt Home hub. (If g.inp is enabled the speeds should be even better)

G.inp is off and has been off since the start, according to dslstats, not sure if its enabled on Cab or line does not need it. Its a new cab only been on line 1 month so would have thought it had been enabled but who knows OR
