I concur with /u/VA_Network_Nerd you can try replacing the firmware on your Belkin router, it might fix your problem if it's software based. Otherwise it might be your hardware but you should contact your ISP to make sure there isn't an issue with your modem.

If you are still looking to update your router I've got 2 options which might be better suited for you.

I would go for the TRENDnet TEW-692GR for $49 on Amazon.

Or the WD My Net N900 for $55 from Amazon if you have a Hard Drive or USB that you can plug in to share music or pictures across your house.

Here's a list of advantages over the Medialink:

• 7 Gigabit LAN ports vs 4 'Fast Ethernet' 100Mbps on the Medialink
• 2xUSB ports for media server or printer sharing
• Dual Band router for best balance between speed and range
• 450Mbps 802.11n vs 300Mbps 802.11n
