PPPoE connection on XGS 2100 SFOS 19.0.0 GA-Build31 - slow page loading

Hi, 

I have problem with pppoe connection which I don't know how to solve 

MTU 1492

MSS 1452

no web policy

no ips

no DoS

tried changing port (on port 2 connection was terrible)

Problem is that pages are loading slow, after I press "enter" on url nothing happens for 10 seconds and then it start to looking for page. I checked on multiple pc's, diferent browsers and directly plugged to lan port (without other clients).  Internet speed is about 200 mbps faster on ISP equipment. Behind XG I get around 350 download and 200 upload. 

Maybe this has to do something with dns but I don't know how to troubleshoot.

Thanks. 

Carlo

  • Hi Carlo

    How about you connect PPPoE directly on laptop and what speet test shows ? and output for ipconfig /all for windows system ?

    Please take SSH access of the device and Login to console and execute the command system diagnostics show syslog

    Save the PPPoE interface configuration and check the output command for PPPoE and share the output.

    You may also execute the command show pppoe connection status

    Please refer the below link and update the ppoe configuration : 

    https://support.sophos.com/support/s/article/KB-000035683?language=en_US

    The web GUI only shows the PPPOE WAN connection MTU value of 1500, and this is the physical interface. The command-line interface (CLI) shows the physical interface and the logical interface. The physical interface for the WAN connection in the CLI has an MTU value of 1500. The logical interface displays an MTU of 1492 and is always deducted by eight due to the PPPOE overhead. 

    The only way to drop the MTU for a PPPOE connection is through the web GUI. For example, if the physical interface is 1500 and an MTU of 1484 is required by the PPPOE connection, drop the physical interface to 1492.

    To change the mss or mtu use below command

    console> set network mtu-mss PortB mtu <value> mss <value>

  •   Hi Carlo 

    Please share current status  for interface speed after expanding Port 2 under Advance setting and logs for below command

    tail -f /log/dgd.log

    tail -f /log/networkd.log

    tail -f /log/dnsgrabber.log

    console>tcpdump ‘host sophos.com

    Might below command helps?

    console> set network mtu-mss Port2 mtu 1492 mss 1412

  • A good indicator of troubleshooting is developer mode of your browser.

    Press F12 and check the Network tab. 

    There you should find an information about delays.

  • Can you please share how to do that?  

  • My internet speed test show's good speeds but i can't full load any news portal bellow 90 seconds, or even speedtest.net

  • Here is a good video how to do this: https://youtu.be/e1gAyQuIFQo
