My motivation with the firmware upgrade to a Zyxel router was all in aid of being able to run DSLstats.
Some background on my issue which is low throughput.
The desktop experience is very noticeable delays in opening web pages and necessitates the use of an add blocker.
Tried 5/6 makes of routers and several computers.
Over 20 BT/OR engineers visits, do usual magic box tests always pass 100%
ISP KDB and Brag tests always very good/excellent.
Cable length to cabinet 170 Mtrs.
Profile 0.128M-80M Downstream, Retransmission Low - 0.128M-20M Upstream, Error Protection Off
Sync 79.999 19.999
Max data rate 92.372 26.873
My BT/OR Guaranteed minimum speed down 70.
BT availability checker line rate 80/79 & 20/19.
My downloads speeds increase by 5-6 Mbs after a DLM reset which lasts for rest of day.
Engineers (using own laptops) speed tests mid 50 down 19 up ( same as mine on a most days but can often be lower)
But completed ticket to ISP always says "achieved the expected speeds".
OR removed "test head" result 76 down 10 up, gone 2 hours later.
2 models of Zyxel routers found to be unable to detect they are connected to Vdsl cabinet.
Can setup manually but............. are all sections of firmware then loaded correctly ?.
Same speed results from a range of test sites.
TBB test results with useful graphs.
Mine

https://www.thinkbroadband.com/speedtest/1599025306377395055Spoken to 7 neighbours on a range of ISP's all with similar poor speeds.
It appears as though all, 70 some, users on this cabinet are affected.
2x SKY users told they can't have 80/20 package due to network issues.
One of them just renewed his contract and is now only guaranteed 10Mbs.
If the change of ISP was a solution I would have done so ages ago.
My conclusion is there is fault at the Huawei AIO cabinet but how to get BT's ISP support desk to escalate the fault to a higher level
