Wifi speed problems on utm 9.705

Lars Otto Skau

Hi.

i have a UTM 9.705 versjon up and running.

i have been using sophos for some time. and now i have a speed problem for my wifi.

I have a amplifi alien router NEW.  i have connected this on my lan. ang get poor speed download, but good upload speed.

I have a fiber connection 500/500. and i get full speed directly to my isp modem.

if i connect my alien router before my sophos i get full speed up and down. ( thats modem-router)

so my que is, is there a setting or something that is affecting my speed down on utm? i have gigabit lan cards innstalled. 

i have a home user licence on my utm.

Lars

    Speed is affected by your web filtering setup and the hardware you are using.  There are a couple of things you can do to help, but I would also try turning OFF Web Protection just to test it and see if that is your bottleneck.  Web Protection > Web Filtering > tick the slide to off at the top right.  Click 'Apply' at the bottom and test your speed again. 

    If your speed is obviously faster, then you may have a hardware bottleneck in your UTM, which would most likely be your CPU.  You can also run the same test on your IPS, and if it's slow there, it's probably Snort and CPU.  Both are due to the filtering that Sophos has.  You can SSH into the UTM and run a couple of commands to help this run better, but I would check these out first and try it to see.

    Hi. i have now debugged everything without luck. so i set up a new server with a clean innstall of utm. without use of  backup , and it seems my problem is gone.

    so i think the issue lies somewhere in the rules or installation of old utm. not hardware.

    thx all for help on this.

    Yes, I have too many times run into this very same thing.  Glad it's at least working for you, and too bad we can never really figure out why these issues take place.  Users get so frustrated (myself included) we just have to bite the bullet and start fresh, because our time just isn't worth it to problem solve, and much more efficient starting over.
