DHCPOFFER lost in transit :-)
Hi everyone!
I have been facing some problems with my home network. All computers are
networked wirelessly and I am using a wi-fi repeater to strengthen the
signal upstairs (it's two floors).
The desktop PC (server) has been running mainly without problems, but
the laptop upstairs was often disconnected. My cellphone (which supports
wifi) mainly couldn't connect at all.
Problems used to cease when I rebooted the router and/or repeater but
only for a couple of hours.
I was suspecting the router (Planet), so today I got a new router from
Linksys (X3000) which I consider respectable because it's a subsidiary
of Cisco.
Well, the laptop hasn't disconnected yet, but my smartphone doesn't
connect at all. It's stuck at the "receiving IP address" stage.
The DHCP server runs on my desktop so I have complete access to it. The
X3000 is configured as a DHCP relay.
Syslog shows the DHCPDISCOVER request received from the desktop, and
answered with a DHCPOFFER (both via the router). But the packet (or
whatever it is, sorry) never arrives, or if it arrives, is ignored by
the smartphone.
I don't know much about Android (which the cellphone is running) and I
would prefer to leave it alone if possible.
Do you have any ideas about the cause of this problem?
Sorry for the long post.
Good evening,
Panayiotis
