Wireless AP self-destructed while away...

meatflowermeatflower Registered User regular
I left for a trip two days before New Years, when I came back yesterday both the Mac laptop and my Eee were not online. Been running the Airlink101 AP431w for over a year now, never had a problem. Now, both machines cannot acquire an address through DHCP. After some time the Eee will assume a 169.254.x.x address, which I've read is from the range XP assigns when it gets no DHCP response.

I've restored factory defaults, reloaded the latest firmware (only available as well). It's definitely the AP itself, as these are two completely different machines that were both connected to it before I left and both were not working when I returned. In addition, they're both able to join and get addresses from my neighbors unsecured wireless router.

There's no option anywhere on the AP's admin page for turning on/off DHCP, the only reference being if the AP itself should find its address that way or be static. After extensive Google'ing I was able to Telnet into the AP and run some commands that initially told me the DHCP server was off. It was definitely operational before, I find it hard to believe somebody else Telnet'd into the damned thing and deactivated. I tried to simply turn it back on but it has no idea what range to assign addresses from...wants a WINS server, and a bunch of other stuff that's just a little over my head. Doesn't seem right that I should have to manually assign all this info when it did it automatically before.

I've tried just setting up the computers with static IP's and while they do gain connectivity to the AP (I can access the admin page from them), they can't ping the main router and hence have no internet access.

Kind of at my wits end here, should I just buy a new access point?

    Is this a wireless AP or a wireless router?

    I ask because DHCP would be off if it were an AP passing DHCP requests back to your main router.

    Did you use the software "Restore Defaults" or the hardware reset button?

    It should default to DHCP On.

    Sounds like a configuration problem considering you can get them to connect with static addresses and access the admin panel; under those circumstances I would double check the gateway and see if you can ping the gateway. Also, you definitely don't need to configure a WINS IP address for DHCP or rather, if you did you would know.

    Yeah it's an AP, so I guess there is some kind of breakdown between it and the router then.

    The AP is connected to a 4-port switch, which is then connected to the router, through a Homeplug device (ethernet over power). It's rather convoluted, I guess I need to get into the web admin page for the switch but it might just be a passive device.

    e: And just to clarify, I have the Mac now hooked up to the switch via ethernet and it's online so the switch seems to be good.

    e2: I can also get to the admin page of the AP from my main computer which doesn't even go through the switch, but is hooked up directly to the router. This seems to suggest that the AP should be able to get DHCP assignments from it.

    AP is going to - most likely - just pass DHCP requests along ie check your routers DHCP. You could also wire yourself into the switch to check the status of your DHCP server.

    The router assigned an address to the computer I'm on right now through DHCP just fine. I'm going to update the firmware on it though, since it's from 2004 and they have one from 2006 now.

    Since your received a DHCP address then the point of failure is your AP; could be a configuration problem or dying hardware.

    This seems bizarre.

    I Telnet'd into the AP again and ping'd the router, and it worked. Why won't it pass the DHCP requests? :x

    I guess it really is dead...

    • Check the port the AP is plugged in, might be good, might not be. If it's not, replace the switch.
    • Set static IPs and check to see if everything gets all hunky dory. If it's fine, likely your router is bad.
    • Try to plug directly into the EoP plug to troubleshoot if it's an issue with the that or if it's just your wireless AP is having an issue passing DHCP back and forth. If it's the EoP plug, you may just need to find a different solution, if DHCP still isn't working. If it works fine with the EoP, it's likely your AP at this point.

    Any reason you're using EoP? Would it be impractical to move or run cabling?

    Switched ports on the switch, no effect. I set static IP's before and the computers couldn't ping the router, even with that set as the gateway. Keep in mind the AP can ping the router, as well as be accessed from computers connected to the router only. I've kind of already eliminated the switch and EoP because I hooked up the Mac laptop directly to the switch and it got an address through DHCP from the router.

    And yeah, those are exactly the reasons I'm using EoP. Actually have three of them in total, and they've always been great, totally transparent.

    Check your netmask when you are configuring your wireless computers with static addresses. DHCP requests are sent to the broadcast IP address.

    Just been letting it default to 255.255.255.0 which is what everything is on.

    From what you're saying, it seems like it's the AP. The fact that the AP can ping the router is a good enough indication that there's an issue with it's radios probably.

    Yeah, got my monies worth I guess...thing was like $20 and it worked a good while.

    I'm moving out in two days and I'm the only one who was really using it anyway (that other laptop is pretty much a desktop machine now so the wired connection is fine), not even gonna replace it.

    So uh...solved? :lol:

    Thanks everyone, I appreciate the help.
