Oh yeah. 100%.

good suggestion to find out first whether the network as such is dead or
just the name resolution or something else.
Also check whether dhclient is running ('pidof dhclient') and grep in
the logs ('grep dhc /var/log/messages | tail -10).
Then we can look further.

I haven't tried the older kernel, is there a suggestion on which particular
one I should try? I'm also not too clear about how I would go about testing a
diff. kernel...
good suggestion to find out first whether the network
as such is dead or
just the name resolution or something else.
The network's fine, as restarting rcdhclient temporarily solves the problem.
Also check whether dhclient is running ('pidof
dhclient') and grep in
the logs ('grep dhc /var/log/messages | tail -10).
'pidof dhclient' didn't return anything, nor did 'pidof
rcdhclient'. Even
when name resolution is working fine, neither command returns anything.
There's nothing in /var/log/messages about dhclient, except for the messages
generated by restarting it.

If it dies it should log an error.
What about dhcpcd? (Is there a certain reason why you use dhclient?)

Well, apparently, I'm actually using dhcpcd, according to ps. The dhclient
bit came into play when I was trying to figure out how to work around this
problem. I've got a more-or-less stock SuSE installation going on, nothing
fancy, especially in the networking area. I don't know much about the
particulars of what's going on with all of that, so I've left it alone.

Ah! So while the DHCP client is running, the network doesn't work though.
Nope. No errors being logged.
Strange. Can you set DHCLIENT_DEBUG to "yes" in
/etc/rc.config.d/dhcpcd.rc.config and restart the network? And, as I'm
still not clear about what your situation is when the network is "down",
can you check 'ifconfig -a' in such a case? Ping your own address? And
in addition look for messages like "transmit timeout" or similar
messages in /var/log/messages that might come from the driver?
Do you have access to the DHCP server logfiles? They could also be
helpful.
To ultimately determine whether it is a DHCP or driver problem, try a
static configuration instead of DHCP:
rcdhclient stop
ifconfig eth0 192.168.0.1 broadcast 192.168.0.255 netmask 255.255.255.0 up
route add default gw 192.168.0.5
(or whatever the address is that you last got from the DHCP server)
...and see the problem turns up as well.
The names are utterly confusing, which is neither your fault, nor mine :)

I'm a bit unclear- is "route add default gw 192.168.0.5" a second command
after ifconfig? Also, which address should be used rather than "192.168.0.5"?
My own computer's most recently assigned IP address? My broadcast address?

Ain't that the truth...

"route ..." is a second command. The IP address would be the default
route of your subnet (if there is any), check 'route -n', the line that
starts with 0.0.0.0.
(Another way of setting the interface up would be to rcdhclient restart
and 'killall -9 dhcpcd', that leaves the interface up)
But anyway, this doesn't look like a problem with the DHCP client. The
DHCP client just sits there and waits. It looks more like a driver
problem. It would be most promising to try a different kernel, as it was
suggested earlier in this thread.

So, it looks like it's getting an IP addresss for
the remote host, it just
can't get there. What the heck is going on here?
Regarding the next question, "ifconfig -a" looks normal (I've still got an
IP
address, and other stuff seems to be set properly). That is, it looks the
same when my network is working and when it isn't.
So the interface is up, but it doesn't work.
