Sorry for this misplaced e-mail, but I just wanted to see if there are
anyone who could give me some ideas about fixing a WRT54G router with
network problems...
My WRT54G (v2) router seem to have died recently... I'm not sure if it's
the bad weather with lightnings and thunder which broke the network
interfaces. (nothing else has broken)
It's up and running with the serial console port, but it doesn't receive
the network packets correct... It looks like the router's network
transmit and receive are malfunctioned. After booting I can see
arp-entries in /proc/net/arp after some tries, but it never sends any
tcp-packets.
I have tried to delete the nvram and make it initialize it from the
beginning, but the problem is still there.
I tried to re-flash the CFE-bootloader on the JTAG-interface with a
fresh copy, and it didn't help.
One thing I noticed was this row showing (~20 times) during reboot...
"The chipset is BCM4712 + ADMtek"
Has anyone else seen this on a WRT54G router?
Should "wl int" and "wl lbt" work without any errors? It doesn't do
it for me... and eth1 has frame errors too.

If I delete the nvram and reboot I get another strange message
when et.o is loaded the first time. "5325E phy=FFFFFFFF"
This seem to be a sign of not finding the registers on correct
address or something.
