I've been using a wireless router, the Belkin F5D7231-4, to connect to my computer via ethernet and to my brother's laptop via wireless. I understand that wireless connections normally offer worse performance, but the router is plugged in through a cable to my own computer.
At a low-traffic time during the day, I reach 13.16 MBPS down/2.07 MBPS up when plugged directly from my modem to my computer. At the same time during the day, I get between 5 and 6 MBPS down/<2 MBPS up when plugged in through my router. I use Optimum Online in New York--the promised speed is 15 MBPS. 13 is not much worse, but 5 is not really acceptable performance...
Can this be an issue with my router or do all routers provide this kind of comparatively poor performance?
I had a similar problem with my Netgear router.
Only solution for me was to replace it with a model that had better throughput.
So I bought a FVS338 and sold my FVS318 on ebay.
My connection is capped at 10Mbps but now I get the full 10Mbps
