      Hi,

      i got a big problem on pfsense 1.2.3 on alix2d3 (no trafficshaper) and 4 vlans. Some costumers reported very slow connection.

      I checked ping delays : from 25ms - 650ms. There are no errors on WAN interface (no in/out paket errors). So there is no cable problem i think.

      Some days before i installed an compex wlan card with external outdoor antenna.

      Is that too much for an alix board?

      Or is it caused by provider?

      Hope u can help.

      cya

      Pfsense running at 11 Locations
      -mobile OPENVPN and IPSEC
      -multiwan failover
      -filtering proxy(squidguard) in bridgemode with ntop monitoring

        There is a wide range of possible causes for "slow connection", some you might have a degree of influence on, others are entirely out of your control. There is nowhere enough information here to give grounds for suggesting a single cause.

        Here are some approaches you could take to investigate.

        Ask the people reporting "slow connection" when they observed it and to what site(s)? (Maybe the site(s) is/are heavily loaded.)

        Has the first page of a browsing session been slow to load and then subsequent pages loaded comparatively quickly? Maybe your DNS is slow.

        Take a look at the pfSense RRD Traffic graphs (web GUI: Status -> RRD Graphs, click on Traffic tab) for your WAN connection - maybe your WAN connection is heavily loaded for sustained periods.

        Take a look at the pfSense RRD System graphs - maybe your CPU is very busy for sustained periods.

        Edited to remove accidental overstrike. (I should use preview more often.)
