internet connection through the router is very slow and timesout when browsing sites

I am using the HAP lite router, using default settings for “home hotspot”. My internet connection through the router is very slow and timesout when browsing sites. If I replace the router with an dlink router, everything works correctly.

What are the settings that could interfere with internet usage on this router?

HAP Lite is primarily intended to be a simple access point. I haven’t played with one to experience the performance, but in general, I would suppose that a more robust router like the 850 or 2011 might give you better performance.

Hotspot is definitely going to add some overhead to your packet processing because it adds extra rules to the firewall chains and causes the router to do a lot more inspection of packets.

Try enabling fasttrack if it’s not already turned on. (by putting a rule early in the forward chain which matches connection-state=established,related and action is fasttrack, and a second rule right after it which is the same, but the action is “Accept”)
