Bad throughput after 9.30*

My guest WLAN (separate zone) is unusable after upgrading to 9.301. My other two WLANs that are bridged to LAN works fine.

Same performance issue here with separated Zones on five AP50 on a 220 with 9.302-2.
Changing the MTU did not really make anything faster. (measured with iperf)

@home 120 + ap10
@work sg325 + ap30's

@home 1400 mtu (normal speeds) other value here are d/l with 2-60kb/s instead of 120mb/s
@work 1432 mtu (normal speeds) other value here are d/l with 2-80kb/s instead of 100mb/s

I already posted this a while ago in the beta forum.

Probably this got not fixed, if still issues around. However - I´m running my separate zone networks since october (since I posted that issue - totally forgot, that I´m not running default MTU since 1,5 month) with a MTU of 1280, which seems to behave quite nicely in view of low latency and high throughput...

EDIT: Just tested it again with 9.303 and AP100. MTU 1500 performsnow better than 1280 - get full Internetbandwidth of 50/5 through the air with good ping times of 14ms (with web proxy, IPS, AppControl, ATP and everything else on ;o)) Will test later with a AP10 too to make sure it´s not an AP related issue...

Edit (again 15mins later...): Ok...thoughput started to suffer again 10-15mins later. Got again only ~1,5MBit/s download via eparate zone. Went back to MTU of 1280...Will point the WIFI dev team to that matter again...

Updated my post with results for 1280. No change whatsoever with 1280 instead of 1500 - or with anything in between.

Cheers - Bob

With MTU from 1400 -> 1499 you get the best throughput, anything beyond 1400 get's you "stuck" [;)]

Hi,

For info I just tested with 9.304, and the issue is still not resolved...

I have written to support.

Where do you set this MTU? I don't see wlanx interfaces on my UTM... must be looking in the wrong place?

Interfaces and Routing --> Interfaces --> New Interface

in Hardware you choose your wlanx adapter and under Advanced you set the MTU [;)]

Hmm ok I found it for the Guest network (changed to 1280) but how can I change the MTU for the Private (bridged) SSID (or is that not possible?)

No it follows the internal network adapter, BUT the issue is ONLY with SEPERATE ZONE WIFI [;)]
