I had this router on an Eircom connection as well, and saw the same
problem. The router was acting as DNS server for the local network, and
configured DHCP clients with its IP address for DNS. The problem
happened when an IPv6-aware client sent it an IPv6 (usually AAAA) query.
The router wouldn't respond at all, not even returning NXDOMAIN. After
a while (30 seconds I think it was), the client would timeout and try
for the IPv4 (A) address.
Disabling IPv6 completely might solve the problem, but what I did was to
set my nameservers statically rather than via DHCP. As for what to set
them to, if you have a look on the front page of the router's web
interface for the settings the router is using itself, then edit
/etc/resolv.conf to use those addresses instead of the router's IP
address. That file should look something like:
Changing it permanently will probably require using a GUI config tool to
make sure those settings don't get overwritten next time you do DHCP.

Can you not ping from the Linux box to the outside world? To the
router? If it still happens, please show us the output of the ping
