WHR-HP-G54 / v1.23 / WDS - routing fine, but no web interface or telnet: ideas?

    Hi all,

    Greetings from rural Uganda, where I'm helping to install a wireless network for a charity hospital.

    I'm using Buffalo WHR-HP-G54 units with external omni aerials, connected as a WDS network (one central WDS AP, two or more WDS 'repeaters'). I've flashed the routers with v1.23.1607 (not the ND version, because it didn't allow Intel 2200bg users to connect).

    So far I've installed the core AP which is configured as WDS + AP (no DHCP, no WAN - those are handled by another router), and one 'repeater', also configured as WDS + AP.

    From an end-user's perspective, everything works fine - you can connect to either AP and get an IP address from the DHCP server, route traffic over the WDS link, connect to the internet. From my perspective, it's not fine because I can't connect to the web interface on the 'repeater' AP, or telnet into it. I just get timeouts when I try.

    Have you ever known the telnet and httpd daemons to stop working, but the AP carry on routing traffic? Is there some configuration option I've set which is known to crash these services?

    When I reboot, telnet / httpd seem to work again for a while, but then stop. Of course I can't view the logs because I can't access the router :-(

    Any ideas?

    Look forward to your thoughts.

    Hello edjones!

    Please give more details like IP-adresses and settings of each router.

    Interestingly, things seem to be working again now, and I can reliably access the web interfaces and telnet both APs. The network topology looks like this at the moment:

    Internet router <--(wired)--> Core AP <-- (wireless, WDS) --> Secondary AP

    In due course there will be more secondary APs linking with the core AP.

    Nothing particularly noteworthy about the settings: the DHCP server is on the internet router (which isn't relevant to this problem), the 2 APs are running as WDS + AP, no DHCP obviously, no local DNS caching, no bandwidth logging. The only peculiarities in the installation are the external antennas (so I'm using antenna 'B' in the Tomato config), and the fact that I'm using Power over Ethernet. To mitigate losses in the cable I've installed 12v PSUs at the bottom end and 5v voltage regulators at the top (which I've tested under load and provide 4.95v).

    Since I posted the question, things seem to be working OK - I can access the web interfaces and telnet both APs, and there's nothing unusual in the logs. And even when I couldn't access the web / telnet interfaces there were still no problems routing traffic across the wireless links.

    Hope this clarifies. Any other thoughts? If not, I might just monitor and see if the problem re-emerges. Don't like not knowing what the problem was, though :)
