Slower VDSL2 with Billion 8800axl versus Huawei HG633 !!

[Dink444]

It was 2 weeks ago I upgraded to TalkTalks Fibre Speed Boost 76 Meg , previously I had TT Fibre which gave me 38 Meg , I only live 400 yards from the main exchange in a small town . All line tests for this area say 75 Meg expected speeds.

I also have a Billion 7800n connected as a secondary access point via LAN1 to LAN1 and setup and working fine , it was 2 x 7800n's but I upgraded to the 8800axl to be the master because 7800n has no VDSL , that was over 6 months ago and this is the first problem.

When testing I remove ALL the LAN connections and turn off 7800n so its a basic 8800axl with Laptop on LAN or wireless ( HP 8740w Quad/Nvidia 5000m/8G RAM ) and plugged directly into main BT socket , no phones plugged in either.

Testing over the last 6 months the Billion seemed more responsive and worked aswell as the Huawei if not better , I could do Speedtest.net and get 30/35 Meg download speeds regularly and the graph would be reasonably flat not all peaky.

However since I have had the Faster speed the Billion 8800axl tests a lot slower than the Huawei HG633 ?

I can plug the Huawei in and get over 60 Meg , but the Billion struggles around the 30/40 Meg most of the time and occasionally peaks to 50 Meg ,
but that's tops I have seen for the Billion.

I have tried " Full Factory reset " and redo all settings , manually on the VDSL and via the " Quick Start " auto setup ,both seem to work and get me
online but I cannot get the same speeds as the Huawei ? I know speeds vary over the day but this consistently is slower I can swap routers and test then swap back and test and the results are always that the Billion is slower by a long way !!

Just this evening I tried the " etec8800axl_2.32e.dh4.afw " to see if it would kick the ADSL back into life and I had seen LAN connected devices being ignored sometimes when on Laptop wireless, resetting all to Factory Settings aswell , did the basic settings and then tried speedtest.net over the LAN no luck , seems to be exactly the same , such a pity as I really like the 8800axl , all other features seem to be perfect , its just the Modem that is having issues.

I have had Billions for over a decade and never had this ? I have enclosed some screen shots of config pages in the Billion maybe " Billion Fan " can see where I have got it wrong , although to be honest I have tried a selection of settings to the point of utter confusion now , these just seem to work best ATM.

Is it a mix of bad settings or is there a hardware issue here ?

Sorry 3 picture limit.

Here are the results that I regularly get now . The line rates are good but I don't get anywhere near them ?

The graph on the TT router was reasonably flat at 64Meg similar to the Billion graph. These 2 screen shots were done 10 mins apart .

Hopefully someone will see where I am going wrong .

Been running the Talk Talk Huawei for the last hour , got a 74 Meg download on speedtest.net same on Think Broadband test,
the Billion has never gone over 50 ?

From looking at your stats, you are syncing at the correct rate, you have a fast path profile (up and down), g.inp is not enabled on your line, and you only have a couple of HEC errors on the downstream, you also have a healthy SNR reading, lowering the SNR won't help

It seems you have done everything correctly, eg isolate the device to one client only, ran a speed test with a wired connection to the router, reset etc. (you can also turn off both wireless 2.4ghz and 5ghz on the 8800AXL and run another speed test with wired connection, just to be sure there are no clients connected to via wifi, also maybe try enabling SRA, Bitswap, outter pair)

The only thing that would cap your speeds, is if you added a QOS rule, but as you stated you reset back to factory default settings, this is unlikely.

I have also checked all the firmware I have (going back to 2.32d.dh12), they all have the same DMT code, so I don' think they will make a difference, and 2.32e.dh4 is the last firmware we had for this device, as the device has been discontinued now

Thanks for the quick reply , Billion Fan , well I will try a few more settings as per your reply over the weekend .

Anyone else out there running one of these on Talk Talk at higher speed ( FTTC 80/20 Meg ) and getting good
results , or is it just me ?
