Help! I've stuffed up my adsl router address

By ChrisBurch ·
I've stuffed up my adsl router ip.

Setup : network 192.168.1.x netmask 255.255.255.0
on a linux network

Original - router ip 10.0.0.2 netmask 255.0.0.0

Firstly communicated with router by setting an ip alias on eth0 of 10.0.0.1 netmask 255.0.0.0 - and communicated fine, so I decided to change the ip to 192.168.1.10 netmask 255.255.255.127 (don't ask me why 127, just thought I'd try it!), then rebooted the router.

Now I can't see it or ping it. I've tried various ip aliases on eth0, and adding gateways to the routing table, but now I'm stuck.

Any ideas gratefully accepted.

Chris

Errr

I'm getting a cold shiver looking at that subnet mask. Trying to remember how this works again. Sheesh. Umm i dunno. Try using 192.168.1.128 with the same subnet mask to reach the router? Tho I'm just throwing out a guess here.

Q1 what make & model is your ADSL router ?

most ADSL router I have come accross have a nice get out button called reset.

normally it is a very small recessed button so you cannot accidentally reset it. This should take it back to factory settings.

Router address

by Raven - cdn In reply to Help! I've stuffed up my ...

Try this:
Router address 192.168.1.10 subnet mask 255.255.255.0
Workstation address: 192.168.1.20 subnet mask 255.255.255.0 gateway: 192.168.1.10

The subnet mask determines the broadcast address and determines if the address you are trying to access is within its local area or if it needs to access it through a router (Default Gateway). It is a base 2 system so: valid addresses are used within that system; 252,248,240,224,192,128.

Remember if you are using a different subnet you will need to change the IP address on the workstation to something within the same subnet to see the new router IP.

Hope this makes sense.

Hi

Thanks for replies

Yup, made me shiver too.

Router - generic conexant chipset, model AR41/2A - can't really find a manufacturer - somewhere in Taiwan, I think - it does have a reset button, but its a flash based os and settings memory, so unless you specifically set it, it won't lose settings with power off.

Raven - I'll try that, may have to separate a machine from the network to do it, because ip aliasing the ethernet card with 192.168.1.x and another broadcast address seems to trash the network.

Will get post back with resuls - thanks again.

Router address?

by ChrisBurch In reply to Router address

Hi

Just re-read your reply

I can't set the router address, because I can't contact it - I set it to 192.168.1.10 netmask 255.255.255.127 - so are the numbers above still valid?
