Can't access router config screen, help!

Crabman

Hi guys,

A friend of ours has now gone live with TalkTalk... I've been trying to set it up but can't access his router config page.

It's a Belkin ADSL2+ Router and according to the literature, you're supposed to type 192.168.2.1 to access it. This didn't work so I tried 192.168.123.1 which worked intermittently then not at all.

I reset the router (it has been switched on with no security for a month :rolleyes:) and since then have had no luck whatsoever. The ethernet cable has been connected to the router at all times.

This is a screenshot of the wireless connection though only went as far as 'limited connectivity'. Not sure what the IPv4/IPv6 is about: http://i32.tinypic.com/wmhyqd.jpg

Any ideas for how to get into the config screen?

Cheers :beer:

You could try disabling the IPv4/IPv6 settings because if I remember rightly I had to disable them to get an internet connection working on a pc not so long ago.

Crabman

Thanks for that - how can IPv4/IPv6 be disabled?

I'm looking on my own system now (same OS - Vista Home Premium, if it matters) but only see the options for automatic or specific IP address.

I suspect the IP is wrong. Try http://192.168.0.1 and then whatever the default admin username and password is.

If they doesn't work then try looking at whatever the current IP is of whatever PC you're on, then you can prob work out the router IP from that. For example, I am currently on 192.168.0.3, so I just change the 3 to a 1 and get the router.

This normally works but post again if still stuck.

Thanks MDE - 192.168.0.1 is something I tried too without success (it works on my netgear router). I'll take a look at the IP address on his laptop.

I'll be taking my laptop with me tomorrow afternoon as I know it works properly and can have a go at connecting with it.

The problem is his router and laptop are both new so there could potentially be some kind of fault on either which is causing these problems... does that sound likely?

On pointing your web browser at http://192.168.2.1, you should see the router login page below. As no password is set by default, you simply need to click the submit button.

Could this be a vista software problem? have you looked at the belkin site and checked if any new firmware is available you may have to use your other computer to see the router and upload the firmware (if available) to the router

It'll usually say limited connectivity if it's not been able to have the router's DHCP server assign you an IP address automatically, for whatever reason.

Your pc will probably have assigned itself an IP beginning with 169.

I'd try connecting to the router directly with an ethernet cable to see if it DHCPs you an IP fine that way. If it does, that points towards there being a problem with your wireless setup. If not, you can manually asssign an IP address and subnet (in the right ranges) and connect to the router that way, and figure out whether the DHCP server has been turned off, or whatever.

I might suggest that generally the easiest way to work out 'where the config screen is' (I.e what the actual IP address is of the management interface of the router) is to look at the properties of your connection - there will be an entry titled "default gateway" - this will (almost always) be the IP address of the interface. (another way if you're slightly more techie-literate is to type ipconfig /all in on the command prompt (start-run then cmd followed by enter) - this will show you a lot of info on the ip connectivity of the PC.

If there isn't one shown (or for example 0.0.0.0) then it means you're not being allocated an IP address by the router so wouldn't be able to route to it anyway - sometimes a good thing to try in these circumstances (to avoid rebooting the pc anyhow) is typing in the following at the command prompt

ipconfig /release
ipconfig /renew

This basically prompts the pc to disconnect itself from the network then attempt to reconnect.

Always happy to give more in depth assistance - just ask.

I suspect this may be due to a Windows Vista problem with WiFi and some DHCP servers. Try the following:

1. Open the registry editor (press Windows key and R, type regedit, then press enter).
2. Navigate to HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows NT\CurrentVersion\NetworkCards
3. Look through the sub-keys and try to find an entry for the Wireless card. When you find it, note down the ServiceName entry (it will be a long series of letters and numbers separated by hyphens).
4. Now navigate to: HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\Tcpip\Parameters\Interfaces
5. Open the subkey that corresponds to the ServiceName you noted down earlier.
6. Look for a value called DhcpConnEnableBcastFlagToggle. Double-click on it to edit it, and change the value to zero.
7. Close the registry editor and try reconnecting the Wireless connection.

Are you connected to the router at all? If so goto start, run and type in CMD hit ok. You will get a command window up. Type in ipconfig and see what it returns against gateway. The gateway is the router IP Address that you need to access, I.E it will look something like this.

ip v4 address 192.168.2.2
subnet mask 255.255.255.0
default gateway 192.168.2.1

ipv6 should make no difference whatsoever though it will return a value.

Crabman

Thanks for all that - I'll try the above when I go over this afternoon :beer:

This is what I plan to do:

1) Find out what the IP address is.

2) (If it's 0.0.0.0) use the "ipconfig /release" & "ipconfig /renew" prompts.

3) Failing which I'll try what benjus suggests with the registry...

Shout if I'm missing something! I'll get a hold of the firmware from belkin's site too if that helps.
