Re: Strange problem

The problem is that I do have quite a few devices and computer that use this
connection and in addition a VoIP device that I can't seem to manage to get
into it's interface and thus won't work without DHCP.
I couldn't find any firmware, especially since it's a special model ordered
and given by my isp (their logo on the router's case and in the firmware is
quite obvious). (Netgear DGN2200*v2)*
I think I'm going to try and replace the router soon if I can't fix this and
if I encounter problems at least the other model I saw at my friend has a
beta firmware with fixes. (Something about them locking WMM off due to some
incompability they encountered without considring the fact that in addition
to obviously losing wmm, on some cards this locks you out from 802.11n mode.

For normal domestic routers, the DNS server handed about by the DHCP server
will be it's own address - it usually runs as a caching/masquerade DNS
server. So you should be able to use static configuration quite
successfully.

Have you checked that the router manufacturer doesn't have a firmware
upgrade that might offer a fix?

Ok, by looking at the dhcp offer packet it seems the lease is set to 1

At the 30 minute mark when the computer requests a renew the router's
bugge
dhcp server sends a nak which causes the disconnect.

Any ideas? (I'm gonna try and replace to a different router with my ISP
but
the other model I know for sure they are offering has it's own share of
bugs)

Well, you could assign yourself static IP, netmask, gateway and DNS
entries
instead of using DHCP to obtain them all.  If you don't have a lot of
computers
to maintain, then this might be a viable alternative for you.  Usually the
only
problem you might run into on [typically] rare occasions is if the DNS
entries
ever change, but it's easy enough to find the new ones if they do by just
changing back to DHCP temporarily.  I have no idea how often that might
happen,
if at all though.  But, if it does happen and you find that it happens too
often
such that it becomes too annoying for you, then you could always use other
DNS
servers that don't ever change, such as opendns.  You don't have to use
your
provider's DNS servers.

opendns servers are listed at http://www.opendns.com/ as:

208.67.222.222
208.67.220.220

I also see at http://en.wikipedia.org/wiki/OpenDNS that there are two
others
listed as well:

208.67.222.220
208.67.220.222

Obviously there are other alternatives if you don't like opendns.
