Need help diagnosing a wireless/wired router problem - D-Link DIR-655

post #1 of 5
Thread Starter 
Yesterday my router was working fine. I went to the store, and when I returned not more than one hour later I woke up my main computer, it was frozen at the login screen. Well crap, I had a game paused, but no big deal. Reset and got windows to boot finally (It's been buggy lately) but didn't have network access. Before I go any further, here are some hopefully-detailed-enough specifications.

Main PC / Desktop-

Asus Crosshair V motherboard w/ intel wired nic
Windows 7 Pro 64bit SP1

Laptop-

HP HDX-16 (slowly dying)
Linux Mint 15

Router-

D-Link DIR-655 hardware version B1
Latest firmware installed.


So anyway, here are the symptoms. Nothing can connect wired. Tested with both the desktop and laptop. Laptop won't connect, running windows troubleshooting and diagnostics resets the interface, which sometimes results in telling me I don't have a valid IP configuration, sometimes fixes the problem for about 10 seconds (shows up as connected, then drops to no internet access, then drops again to no network access). Both computers can connect to the wireless and access the router, but cannot access the internet. When running ifconfig/ipconfig, my laptop gets an IP on the wired connection, but windows appears not to (see below). I have tried resetting the router to factory settings using the hardware reset button, and have power cycled it about 15 million times. Fortunately I can connect to the University wireless in the meantime, but I'd really like to figure out if the router is repairable or if I should just buy a new one. I apologize in advance if I've left out any important information, and will respond to replies ASAP as my class schedule allows. Thanks in advance for the help.


Below this is the results of running IP Config on my desktop. I am connected to my university's wireless network, the network cable to my router is plugged in, and I also have virtualbox installed.

what service provider do you have? Can your university system ping your router?

If you're basically looking to verify that the ethernet jack in my wall is working, with my laptop connected to campus wifi, and my desktop plugged directly into the wall, I can ping my desktop from my laptop and vice versa. With my desktop connected to campus wifi via a usb dongle and my laptop plugged into the wall, I can also ping in both directions. However, with my desktop I can't ping outside the university network (ping google.com doesn't work) but on my laptop I can, both plugged directly into the wall. I can also browse the internet normally with my laptop whereas with my desktop I can't when plugged directly into the wall. With both devices connected to my router's wireless, I can ping in both directions but I can't ping google.

I also just tried hooking up my parent's old Linksys WRT56G that I just replaced for them a few weeks ago. Plugged that into the wall and my laptop and it worked fine (with the laptop wireless turned off, only using the wired connection). Pulled off a download speed of ~66Mbps and an upload of around 18.

Repeated the previous test with my D-Link router and got 25 down and 8 up (could be a difference in servers).

Repeat the test with my desktop instead of the laptop, and windows doesn't think it has a valid IP configuration and so on. So, I think I'm having two problems (at least). One is that the campus network is screwy at the moment, since I feel like I'm getting inconsistent results with my tests and two, I think windows is messed up on my desktop, since my laptop is playing nice with my router now.

I think the biggest thing that helped my laptop work with my router on the wired connection is restoring the router to factory settings through the router's gui rather than via the reset button. The wired connection started working after that.

My memory is that screwy is a way of life for campus networks.

Oh definitely. I reinstalled windows and everything appears to be working now. Seems like my router and windows got screwed up at the same time, or maybe just windows. Not sure. As long as it continues to work.
