Hi,
I compiled an 18.06 system for my ZBT WG3526 router.
OpenWrt 18.06-SNAPSHOT r7161-b84a1c56f3 / LuCI openwrt-18.06 branch (git-18.206.16200-7501bf6)
This router uses the MT7621 processor.
I have found a weird thing: Wireless MAC80211 802.11nac runs at full speed on my Wireless NBN system (Max speed 25Mb/s), so on wireless I measure about 21Mb/s. If I hard-cable (ethernet) my maximum throughput is about 5Mb/s, or about 80% slower. I tried the computer connection as Wireless, then wired, then wireless & found the internet speed was ~5Mb/s, then 21Mb/s with nac wireless, then back to 5 again with cable etc, so the issue is definitely router related. (I could see no issues in the router error log.)
regards, Doug
I will check the direct connect speed later, but in the last few days i have had the computer directly connected to the NBN Terminal device, & the speed there was fine with ethernet (seem to remember 21Mb/s).
My feeling is this is router related, but I need to know how I can check further. (I run PCLinuxOS on my computers)
If your getting 10baseT full-duplex that is going to limit your download speed to MAX of 10Mbps. If you have 10baseT half-duplex that will limit your download speed to MAX of 5Mbps.
Thanks for the responses.
To answer the queries, I was aware of the potential hard connected speeds (was on high speed connection)
Ihave done some more digging, & it seems the issue is related somehow to the time the router has been 'up'. What is weird is that the hard wired speedtest immediately after a router reboot, is really slow: less then 4Mb/s, whereas wireless (NAC) was over 20mb/s. However, if the router is tried after some time (say a day) hardwired, the speed approaches the wireless speed (but is still marginally slower)
I was using SQM, with the download set to 0. When I disabled SQM (rebooted router after!), the speed increased to about 13.98Mb/s (still slower than the Wireless speed).
I will leave the SQM disabled, & check the download speed over the next couple of days to establish a pattern.
(I am wondering if there is a problem in the MT7621 ethernet code). The wireless issues seem to be resolved.
After a few days I might compile a WE1326 snapshot, & see if the same issues are apparent there. (my second router).

Sorry to bring an old topic back from the dead, but I couldn't find any other place mentioning this problem.
I have the same issue, with both of my MT7621A routers (YouHua WR1200JS, ZBT WE1236), when I upgraded them from LEDE 17.01 to 18.06.2 I've noticed approx. 50% throughput drop on Ethernet, wireless is unaffected. I've also enabled Hardware flow offloading on both, things seem more responsive, but throughput is still around 50-55% of what it should be.
My Internet access is 10/100 up/down. I'm smashing 11/107 consistently on speedtest.net on my phone, but barely 10/55 on ethernet on my high-end desktop computer with a 1gbit network card (yes, 1000/1000 is negotiated), using the same test server on speedtest.net back to back. Nobody else is on the network, this is a consistently repeatable controlled test
.
I had great ethernet performance before this upgrade (identical to wireless), anyone knows what happened and how to debug/fix this? I was suspecting a failure with my 1gig powerline adapters, but I hooked up directly to the main router and I'm having the same issue: half the Internet speed I'm supposed to be getting....
