WAP321 slow download speeds

[erik175241]

Hi!

I have a WAP321 access point in a home environment, powered by PoE, and sharing two VLANs with VAPs, one home network, and one guest network.

The problem I have is that my download speeds are very slow, while my upload speeds are fine. I usually get around 20-40 Mbps down (access point to device), and 60-70 Mbps up (device to access point). This is tested both with speedtest (I have 100/100 fiber) and iperf on the local network.

I am happy with the upload speeds, and would like to have similar download speeds.

The only thing I can think of that would have this effect is QoS, but I can't find a way to turn QoS off completely. I don't really need QoS at this point. I have these QoS settings right now:

I need to use mixed n/g mode for compatibility, but I have tried 5 GHz and there was no difference. I have also tried different channels but found that channel 6 that I was already using was the best. I have also tried to use 100% transmit power with no difference. 20/40MHz was slower than 20 MHz.

My diagnostics file is attached. Any help would be appreciated.

Erik,

Try testing another device does it behave the same way ?

Yes, I have tried with several different devices, three of them beeing laptops.

Sounds like you tested this on your local network as well. Have you tried to transfer from one laptop on your wired and one laptop on the wireless.. Same results ?

Yep, I have tried iperf from wired gigabit to wireless, both ways. I have also tried file transfers. same results.

I don't have this model ap to test. Are you on the latest code ?

Yes, I upgraded the firmware about two weeks ago, and when I checked yesterday it was still the latest.

No, google is of no help at this point.

Maybe I'll have to give customer service a call...
