Hi all!
I have problem with my home WAN to WLAN bandwidth, which goes no more then ~40 Mb/s, meanwhile all other connections shows great results
*color lines means trials of connection for test.
I already spent arround a week for a various tests and expirements. I tried to disable firewall at all, configuring everything from zero and even fresh netinstall.
Please help find the root cause. Here is different test results:

All other wireless devices in network working same way: good upload, terrible download, thats why I need to find a solution for it
WLAN and ethernet2-5 ports in RSTP bridge. I will post any required configuration options
Thank you in advance!
Seems I have found cause of slow download, but I’m not sure why it was seen only throw wireless
I connected ISP directly to PC and measured packet loss with UDP iperf3 test
This is upload, everything is just fine, packet loss only (0.63%)

iperf Done.
On higher speeds losses rises
On slow speeds 0 loss.
So I have 2 questions:
- Am I write that this packet loss is a root cause for my slow download speed?
- Why slow download was seen only via WLAN? And via LAN it was >90 Mb/s?
Finally seems it is not a cause of my issue, it’s just an iperf3 bug, as with iperf2 this test runs perfrectly, and I also found a lot of forum threads with same problem of iperf3.
So my problem is still present and doesn’t solved, any suggestions? Help me please
i see you are marking with red color mostly the test conducted across wlan.
I think the performance its ok for a 2.4ghz radio
The most strage thing is that WLAN - LAN speed is very good, but the WAN → WLAN speed is less few times
I´ve got the same issue here. Download Speed WAN → LAN 94 MBit/s, Download Speed WAN → WLAN 22 MBit/s.
After switching Wifi to 2Ghz N-only the Download Speed increases up to 48 MBit/s.
