We have a 25Mbit connection comming in through a cable in the basement, going through a modem that is connected to a RVS4000 small buisness router on the first floor, that acts as the single NAT. Connected to that in parallel we have 4 wireless b/g or b/g/n routers of various cisco/linksys models, one for each floor, each with DHCP disabled.Over the last few months there have been some issues with the router and I'm curious if there is anything that can be done to solve them.The firmware of the router is the latest at the time of this writing, V188.8.131.52

1. The router will occasionally lock up and completely stop responding to DNS requests. Attempting to open a website will result in browsers giving their standard 'DNS Lookup Failure' messages. The router will also become completely non-responsive when trying to access it via its IP address (standard 192.168.1.1). No username/password dialog appears.However oddly enough IRC and other chats like skype will still work fine.Restoring Factory settings has not worked. This issue has gotten to the point where this happens about once a day. Restarting the router will fix the issue. While I think the issue may sometimes resolve itself, it could also just be one of the other people in the house restarting it manually.I'm assuming that the router is to blame here and not the cable modem in the basement or the DNS server of our ISP, mostly due to the fact that the router becomes unresponsive and won't let me log in as admin when this happens. also restarting the router, not the modem, seems to fix the issue.
2. The router's log is always empty Specifically I have enabled 'Output' and 'Local Log' as you can see here:
3. Issues with some people hogging bandwidth With 25 people and a 25Mbit connection each person in the house should effectively get about 125KB/s of download speed, especially since not everyone is always using bandwidth. However it can happen where one person is, often without knowing it, hogging a large chunk of bandwidth and slowing the network down for everyone, such as downloading multiple large files from different sites, streaming high-quality video, etc.I would like to know if any of the following might be possible to do with this router: See the bandwidth usage per individual MAC or IP address on the network over timeLimit the amount of bandwidth a specific MAC or IP address can use. Make the distribution of bandwidth more fair when a few people are using far more of it than other people.
I have at times resorted to limiting P2P via IPS in the past, and of-course that does work somewhat, but that's not ideal. I'd much rather just know who is doing it, and specifically by how much they are slowing other people down. While the IPS page will list the IP addresses of those trying to use P2P when it's disabled, there is no way for me to really quantify how much bandwidth they'd be using otherwise, and this doesn't at all include things straight-up HTTP downloads.In any case, this router should easily be able to handle ~25 simultaneous connections, right? Are there any settings that I should make sure to enable or set to distribute bandwidth more fairly, given the setup we have?
4. The IPS report chart is not readable.This is a bit of a nit-pick, but the IPS report chart is basically not readable because the colors used in the key are identical in color. Can you tell the difference between the colors of 'Network Traffic' and 'Attack Counts' in the key at the top? They could have used any two colors that are at least somewhat distinguishable, even light grey and dark grey would have been better, not magenta and another magenta.
