TP Link ER5120 limitations: lacking and disturbing features

Posted by jpluimers on 2016/03/18

Mikrotik have statistics and way more features. The most lacking or disturbing features on the TP-LINK (none of which are mentioned in their documentation):

  • The documentation mentions you can enable Enable Bandwidth Based Balance Routing then select the WAN connections to combine but that doesn’t work at all, even if you follow the bandwidth steps carefully.
  • Balanced Routing work when you perform these steps as mentioned at time point 457 in this video
    • Enable Application Optimized Routing
    • Enable Bandwidth Based Balance Routing
  • Virtual-Server table can only handle 32 incoming port redirects; you get the message “Cannot add more than 32 Virtual Server entries” like in the picture below.
  • No IPv6 support
  • No way to show any statistics as graphs.
  • Every once in a while the web interface becomes really really slow which only a reboot can resolve.
  • You cannot have one of the WAN connections have multiple IP addresses.
  • Local DHCP clients are not added to the DNS proxy which means you cannot resolve them by name.
  • TCP Sequence Prediction: Difficulty=0 (Trivial joke)
  • You cannot configure how often to check WAN connections

On the other hand: when you do balanced routing indeed bundles all the WAN connections, configured Virtual Servers do work well and WAN specific routing settings to what they need to.

Verdict: fine for home use, not good for real multi-WAN use.
