wifi: one VLAN much slower than the other!?

Hi,

I've got a Netgear WAC720 with two wifi networks, one using VLAN 20 and one using VLAN 30. Both have no speed restrictions on them. Both are 100+ Mbps using Ethernet.

The wifi with VLAN 30 gives me (on my iPhone) speeds of 50 Mbps but the wifi with VLAN 20 only 0.15 Mbps!? any ideas why that would happen or how to resolve this?

Thanks a lot!

A duplex clash could cause that. If you have the WAP set to full and the switch it is connected to to half, generally throughput will be slow and sporadic. Check either both ends are set to auto, or both set manually to the same duplex.

Do you get proper throughput with a laptop connected to the CAT5 cable that plugs into the WAP?

One SSID works fine, @malmensa, so it's not duplex on the AP's switchport.

Are you using 2.4GHz on the VLAN 20 SSID but 5GHz on the VLAN 30 SSID, or have you applied different QoS policies to each SSID in the AP's config?

Hi,

I'm using 2.4Ghz on both wireless networks.

I've not defined any QoS policies ...

Ok, I've identified and solved the problem myself!

My 3COM switch has something called a 'PVID' parameter. It referred to VLAN 30 (my 'secondary' network), I switched it to VLAN 20 (my main network) and now both wireless networks run equally fast!
