Cant access linksys configuration

[xxarthur33xx]

hello. I'm having a bit of trouble with my router.

When ever I try to go into my router, it doesn't connect to it at all. On vista, I use 192.168.1.1 to get into it, but on Ubuntu it doesn't even try to connect. I tried 192.168.0.1 and it says its loading, but it never loads.

from route

$ route

(I changed it to 192.168.1.1 because another thread said it should be your routers ip)

If you need anymore information, just ask.

I presume the Ubuntu box is not the router - and does not have the address 192.168.1.1. The (second) default gateway - using "lo" as interface - may be at least partly responsible for the problem.

How do you get into your router - Firefox?

[xxarthur33xx]

Yea, I'm on wifi. My moms computer is the base for the wifi. Its an old wrt54g wireless router. Im upstairs and I connect through firefox. I can get into the config on windows, but not on linux.

How would I go about changing the lo to wlan0?

[houstonbofh]

There was a version of the wrt54g that was broken in firefox, and with zonalarm on windows... Try installing ies4linux and connecting (slowly) with that.

[xxarthur33xx]

I downloaded and installed the ies4linux and it didnt fix the problem. Any other ideas?

OH, to add to weird things that are happening, when my xampp is turned on, 192.168.1.1 is used for localhost. (I can access my pages on 192.168.1.1 just like I can on 127.0.0.1)

[Iowan]

Didja happen to remove that gateway to "lo"?

[xxarthur33xx]

I dont know how. :(

[Iowan]

(Me neither)
I suspect the information in man route will help. the line:
route add default gw mango-gwmight be modified to:
route del default gw 192.168.1.1 lo

[xxarthur33xx]

hmm, I tried but it came up with an error. I did manage to delete the one with the lo though.


$ sudo route del default gw 192.168.1.1 lo
$ sudo route add default gw mango-gw
mango-gw: Unknown host
$ sudo route add default gw 192.168.1.1 wlan0
SIOCADDRT: No such process
$ route

link-local * 255.255.0.0 U 1000 0 0 wlan0
default 192.168.1.1 0.0.0.0 UG 0 0 0 wlan0

Now what do I do?

[Iowan]

Sorry - my bad. That "mango-gw" line was straight from the man route page.
Can you access the router from a browser by entering it's address: http://192.168.1.1? Might need to restart networking.

[xxarthur33xx]

Thats what ive been saying the entire time.. :P

On my windows partition, I can access my router configuration via 192.168.1.1 on firefox and IE.
On my ubuntu partition, I CAN NOT access my router configuration via 192.168.1.1

I THINK it started ever since I upgraded to HH a while back. I've upgraded from HH to Intrepid and now im on Karmic. I'm not sure if that means anything, but it might be useful information.

[houstonbofh]

Output of the following terminal commands please, from a clean boot.

route
ping 192.168.1.255 -b -c10
arp -a

Thats what ive been saying the entire time.. :P
I believe there was some confusion as a result of this statement:

I tried 192.168.0.1 and it says its loading, but it never loads.

Are you absolutely positive that:
1) You are connected to your own wireless network.
2) Your router is configured to allow administrative access via wireless.

You say your router is an old wrt54g ... what version? Are you running alternative firmware?

[xxarthur33xx]

Im connected to my own wireless network. My mom is the host downstairs. The router goes through her pc and broadcasts to mine and her boyfriends.

On windows vista, I can access my router with 192.168.1.1. I used to be able to do the same on Ubuntu, but it stopped working about a year or so ago when I upgraded to Intrepid (I believe it was Intrepid).
I was thinking maybe it might change for some reason, so I tried 192.168.0.1 and it just showed it was loading. I didnt know if that meant it was trying to connect but there was an error somewhere.

Yes, it is an old wrt54g v5 and allows administrative access through wifi. It has the latest firmware they made for it. I was thinking about dd-wrt, but it is incompatable with my router.

[rclark68137]

Do you know if your mom has made any changes to the router's setup? There is a setting on the router called "Wireless Access Web". It allows you to disable wireless access to the router’s web-based utility. In other words, you would need to run an ethernet cable between your PC and the router in order to access the Linksys configuration at 192.168.1.1

Do you run Firefox with adblock plus? If so, try disabling adblock plus. Any other browser security plugins?

What's the output of:

sudo iptables -L

[xxarthur33xx]

@rclark - No, my mom doesnt even really know how to use a computer, let alone change router settings.

@Dmizer - Thats a good idea. I didnt even think about that. I do have adblock plus added to my FF. I'm not sure what else I have installed for security on my FF, but I'll look when I boot up into ubuntu in a few minutes.

I uninstalled Adblock Plus and some other addons. I tried getting into the router and it still doesn't work. :(

[snip]
You didn't need to uninstall adblock ... just disable it for testing. Adblock is a good plugin, but it can cause problems sometimes.

Are you running Firestarter? If so, just uninstall it. If you absolutely must have a firewall running locally, you should use GUFW (https://help.ubuntu.com/community/Gufw) instead. Is there some particular reason why you need a secondary firewall running behind your router ... which is also a firewall?

[xxarthur33xx]

I though I already uninstalled it, Guess not.

Ok, so I removed that and I tried again..and still cant connect to it. :(

[dmizer]

Try running this command:

sudo iptables -F
Then try to access the page.

[xxarthur33xx]

Tried that command, still doesnt work. this is insane..

After you tried that command, what's the output of: sudo iptables -L

Try rebooting your router. Double check to make sure that your router allows access via wireless. Are you using OpenDNS (http://www.opendns.com/) DNS servers (if so, try disabling them)?

[xxarthur33xx]

Well, after the fresh install fo karmic, It now works, along with ssh'ing into my iPhone and remote desktop. :)
