Changed IP for Main PC, Now Remote PC Doesn't Match

[mattx109]

Due to a problem at my ISP I had to release and refresh the IP of the PC connected to the modem and router. That's working fine now, but the remote system can't connect; it's receiving the signal just fine.

I tried the vague "repair" function with no success, and I released and renewed the address there, but the renew failed.

If anyone could tell me how to input the proper IP at the remote PC, or point me in the right direction if that isn't it, it would be much appreciated.

Are you running Windows ICS? Using wireless on the LAN side?

Are you trying to remote into the PC or do you mean your wireless connection doesnt work?

Thanks for the replies. Sorry for not being clearer. I'm not very familiar with networks of any kind.

The wireless connection doesn't work. The signal is fine. The second PC isn't mine, but I was told that after the new IP was assigned to the first computer it asked once for him to input the new address. He didn't know what it was and it hasn't asked again since.

In looking at the network properties of the second computer it did still have the old IP displayed, but I couldn't find any way to update it to the new one. I tried the "repair" function, but it failed to update the IP. I tried using ipconfig to release and renew it, but it failed to renew and now has no IP address at all.

Ok, what wireless router do you have? or if its all built into the modem, what is the make and model of the modem?

It shouldnt really matter that your main IP from your provider changed.

[mattx109]

The router is a Linksys BEFW11S4.

I'm not sure of the model number of the wireless network card in the other PC, but I know it's a PCI Linksys card.

When I look at the list of available wireless networks on the second PC it shows three. The first is mine and the others are probably from neighbors. Mine is selected as the preferred network. It knows it's there, but the IP isn't right.

What "changes" did your ISP have you do to the router? Is the routers LAN IP still at the default 192.168.1.1 ?

[YARDofSTUF]

You shouldnt have any IP set, should set it to auto configure or auto find the IP

When I set my connection up I use WPA, set the SSID or Name on the router to what I want and then make a TKIP WPA key. Make authentication type Auto in advanced settings.

On my PC with the wireless I view available conenctions, find it by name, click connect and enter my TKIP WPA key, select it as default, and click connect.

I don't know what happened at the ISP. My connection was dead and I couldn't figure a solution, so I called them and they said there had been a problem on their end. They asked me to use ipconfig to release and renew the IP. I told him the new address, he did something on his end, and the connection was back.

When I refreshed the IP I didn't have the router hooked up. Once the connection was back I put the router back in the loop and my connection worked fine. The second PC, although receiving the signal, couldn't connect at all. Looking at the network properties of that computer I saw the old IP address, not the new one, and tried to release and refresh that, too. It didn't work and now displays no IP at all. It still picks up the signal, but upon selecting the network it can't connect.

Interestingly enough, at your mention of 192.168.1.1, I tried to go to that address in my browser to look at my router settings, but it didn't work, giving me the usual "cannot find server or DNS" message.

A little more information:

Navigating to 192.168.1.1 in my browser had always brought me to my router's control panel, but it no longer works.

I checked the tech support area of Linksys and tried resetting my router, but that didn't work. They also have software called NetSet Assistant meant to initially install a router and set up a wireless network. Neither program was able to detect my router at all, yet I have a connection and the second computer detects the signal from the network.

Do you have any PC that's directly wired into the Linksys?

On any PC that can connect to the internet, if you run IPCONFIG, what IP do you get? A 192.168.xxx.xxx? Or a public IP?

[mattx109]

Local area connection is a public IP.

Network Bridge is 192.168.etc, but there's a zero where there used to be a 1. Typing in the address with the zero also results in a "cannot find server or DNS" message.

When you type ipconfig from a working pc, where it lists defualt gateway, try that IP to get to your router, it should be 192.168.something.something

[mattx109]

Local area connection default gateway is 69.162.xxx.x. Network bridge default gateway is blank.

Typing the IP into my browser also returns the same error page.

To reset the router, if its like my WRT54G, hold the reset button firmly for 30 secs.

[mattx109]

Holding the reset button for 30 did make the "Internet" light go out. It returned shortly after releasing the button and there was no change. I still can't access the router's settings.

I also tried to reset using a method listed at the Linksys site last night, which was to disconnect power from the router, then hold down the reset button while returning power. Nothing that way, either.

Is it possible that the connection is passing through the router, but that the computer just doesn't know the router is in the loop? Linksys's NetSet Assistant couldn't detect a router when I tried that last night. (I have an e-mail out to their tech support.) Of course, that would probably mean that it wouldn't be sending a signal, but the second computer is getting that.

[YARDofSTUF]

On the PC that is working, is it's IP 192.168.something.something?

You're bypassing your router.

Broadband Modem==>WAN/Internet interface of Router==>LAN ports of router to NICs of PCs.

What make/model is your broadband modem? I'm betting it's a combo modem/router unit..that the ISP had you reset back to gateway mode.

Taking a wild guess at your pub IP...SBC/Yahoo?

[mattx109]

I have two separate devices. The modem is a Terayon TJ715. Router is a Linksys BEFW11S4. ISP is Adelphia.

So, this sounds now like something on the ISP side?

It sounds like the router isnt even connected.

The router should have the 69.162.xxx.xxx IP

internally it should be 192.168.1.1 and it should start assigning IPs at 192.168.1.100
192.168.1.101
... and so on.

[mattx109]

It's fixed.

I disconnected the router and modem and removed every trace of them from the system. I reinstalled everything from scratch and called my ISP to make sure everything was all right on their end. Seems to be working fine now.

I want to thank everyone for their help. This is by far the most friendly and useful forum I've come across. My experience with this paticular problem was excellent and I'll recommend the site highly. I definately want to stick around and see what other useful information is surely lurking here. The overclocking forum caught my eye...

So thanks again for all your help! :D

[YARDofSTUF]

Odd, but glad its over. lol

Fair warnign, overclocking is addictive! :p
