Have you set specific IP addresses for any of your devices, or are you allowing the DHCP server in the router to automatically assign them? It sounds to me as though there is either something a little odd going on with the router's DHCP server in terms of maintenance of IP address leases when devices go to sleep, or else there may be two devices on your network with the same address and they are conflicting.
Technical details and instructions follow, which I hope I have made as clear as possible!
If you can check your router's configuration settings, you want to look at the IP address, subnet mask, and DHCP server settings. Most home routers by default use IP addresses either 192.168.0.(0-255) or else 192.168.1.(0-255) for the home network. The DHCP server settings should tell you what the first address is that the DHCP server will use, and also how many DHCP clients are allowed to attach to your router. For instance, if the first DHCP address is 192.168.0.100, and 10 clients are allowed, then your router will assign addresses 192.168.0.100, 192.168.0.101, 192.168.0.102, etc., sequentially as more devices connect, up to 192.168.0.109.
You can try "hard-coding" a static IP address on your AVR to get around potential problems with the DHCP server in the router. Once you've figured out what addresses are "blocked out" for use by the DHCP server, simply assign an address that is not one of those numbers, but is between 1 and 254. It just can't be the same address that is assigned to the router itself, which is why you also need to check that number. Then get into your AVR setup, network settings, and manually assign it an IP address - the first three numbers should be the same as your router (usually 192.168.0 or 192.168.1) and the last number is the one that has to be different from the router AND not in the range assigned to the DHCP server. You probably will also have to enter a "subnet mask" which you should make the same as the subnet mask in the router settings (usually it's either 255.255.255.0 or 255.255.0.0), and possibly a "gateway" address which should be the IP address of your router. Sorry I'm not home right now to look in my own settings to see exactly what is required.
I would set a static IP on the AVR (and maybe also your TV, if you're having a problem there too) and see if it takes care of the problem - then you avoid needing to buy a new router... unless that doesn't work, of course.
I do however really like the A820. I just wish I could figure this out!! It's driving me crazy.
