Been having a problem with my router for a while now, might just be because it is really old but here's the problem:

If a lot of computers are connected to my home network someone will get disconnected. They are assigned IPs and it seems like at a certain point (and I don't know how many) you either get assigned the same IP as someone else or something else is happening and you get disconnected - until i soft reset it and it works again which takes 30 secs.

I'd say my tablet, my PC, my sisters iPad, 2 laptops and a netbook is the most that can be connected at one time so that is 6 but that should be fine.

The only way I know this is the problem is because I turned on my tablet and I was online on my PC, got disconnected but my tablet was still connected, this is just after i turned the tablet on so I know my router is having difficulty with IPs, it is like it assigned the same IP to the tablet which then clashed with my desktop and knocked me off.

I see that sometimes the following solves it as well so I wrote a batch file with a menu to execute these commands as I have to do it so often.

ipconfig /release
ipconfig /flushdns
ipconfig /renew

Any ideas? Or shall I just get a new router as this one is old and maybe can't handle giving out that many IPs?

Cheers!
