ARP Cache

bevalese · 10-21-2006, 07:26 PM

I have read previous posts on clearing the arp cache, but nothing seems to be working for me. I cannot connect my daughter to the internet. I have even tried directly plugging her computer into the internet. A year ago she had no problem accessing my network to get onto the internet. She moved out and her boyfriend installed Moxilla Firefox (?). Then she moved back in with us, and nothing I can do allows internet access. I removed the Moxilla, hoping her other wireless setup would be restored. What should I do?

What error messages are you seeing?

Let's start with some troubleshooting:

Click the <Start> button
Click the <Control Panel> menu item
Click the <Network Connections> icon
One of your network connections should be named something like "Wireless Network Connection" --- what are the words in light gray underneath that title?

Double-click that icon to bring up the Wirelsss Network Connection Status window.
What is the Status?
What does it say next to Network?
What Speed is listed?
How many bars of signal strength do you have?

Click the <Start> button again
Click the <Run> menu item
Type CMD and press <Enter>
Type IPCONFIG and press <Enter>
What does the IPCONFIG command tell you?

Thanks, Will. Here are the answers to your questions:
The wireless is connected, firewalled.
Broadcom 54b Max Performance.

Status Connected, Network- Bev (that is the network I want it connected to) at 54.0 MBPS

Ethernet adapter wireless
IP: 192.168.1.101
Subnet: 255.255.255.0
IP address: fe80::290:46ff:fe5f:972ax5

That last bit confused me.

You should see something like this:

Code:

C:\>ipconfig

Windows IP Configuration


Ethernet adapter Local Area Connection:

        Media State . . . . . . . . . . . : Media disconnected

Ethernet adapter Wireless Network Connection:

        Connection-specific DNS Suffix  . : hsd1.co.comcast.net.
        IP Address. . . . . . . . . . . . : 192.168.1.103
        Subnet Mask . . . . . . . . . . . : 255.255.255.0
        Default Gateway . . . . . . . . . : 192.168.1.1

That last "IP" looked more than a bit odd. What happens when you use the DHCP /RELEASE and DHCP /RENEW commands?

Are you seeing any error messages at all?

bevalese · 10-23-2006, 11:35 AM

There is nothing next to that first line... Connection-specific DNS suffix. And the error message said DHCP is not recognized as an internal or external command, operable program or batch file.

Will.Spencer · 10-23-2006, 02:05 PM

Oooppss... sorry... that what mis-typing on my part. The commands are IPCONFIG /RELEASE and IPCONFIG /RENEW.

Can you cut and paste the output of IPCONFIG for me? That last line looks really odd.

What error messages were you seeing initially, before any of this troubleshooting.

bevalese · 10-23-2006, 03:39 PM

For release and renew, if no adapter name is specified then the IP address leases for all adapters bound to TCP/IP will be released or renewed. I can't cut and paste because I can't get on the internet with that computer. But I will type it out exactly like it is listed again.

Ethernet adapter Local Area Connection:
Media State.......:Media disconnected

Ethernet adapter Wireless Network Connection:
Connection-specific DNS Suffix.....:
IP Address............192.168.1.101
Subnet Address.....255.255.255.0
IP Address............fe80::290:4bff:fe5f:972ax5

(That last line is the only thing mentioned for IP Address for Tunnel Adapter Teredo Tunneling Pseudo-Interface ad well as Tunnel adapter Automatic Tunneling Pseudo-Interface. Also the next to last digit (x) I can't tell if it is an x or a division sign).

bevalese · 10-23-2006, 03:47 PM

Will, I apologize for not answering your previous message regarding error messages. When my daughter moved back in with us, she said she could not access the internet on her laptop. Since she had been able to do it in my previous address, I rechecked my connections with my desktop and my laptop. No problems. So I started trying to connect her to my network. I figured that the Moxilla Firefox might be to blame, so I removed it, but I received a message to remove the ARP cache. That is how the discussions on removing that began. I haven't figured out how to remove it.

Teredo? Hmmm... Why are you running Teredo?

Teredo is an encapsulation protocol used to tunnel IPv6 through IPv4 NAT devices.

Are you running IPv6? Almost no one is.

You should probably go into your network configuration and remove both Teredo and IPv6.

IPv4 is the current standard.

bevalese · 10-24-2006, 03:00 PM

Will, I have no idea why Teredo or IPv6 are being run. How do I delete them? Could this have anything to do with the Mozilla Firefox?

Will.Spencer · 10-24-2006, 04:28 PM

Click the <Start> button
Click the <Control Panel> menu item
Click the <Network Connections> icon
Double-click your network connection icon
Click the <Properties> button
Find IPv6 in the list
Click the <Uninstall> button

Or, it might be easier to just delete the network connection, reboot, and let it be re-added automatically by the reboot.

Click the <Start> button
Click the <Control Panel> menu item
Click the <Network Connections> icon
Highlight your network connection icon
Press the <DELETE> key
Click the <Yes> button

bevalese · 10-24-2006, 06:11 PM

I have deleted IPv6, but still no success. She is connected to my network, but has no internet access.

Will.Spencer · 10-25-2006, 04:47 PM

There are two paths we could follow. One would be to list all of the Clients, Protocols, and Services used by that connection and we can troubleshoot which ones are missing and which ones shouldn't be there.

The other option would be to delete the connection, reboot, and let Windows rediscover the connection automatically. That works 90% of the time.

I'm voting for the second option.

bevalese · 10-25-2006, 07:04 PM

Will, I like that second option as well, however I don't seem to know how to delete the connection. I know it seems obvious, but I apparently don't have the delete option. I also discovered when looking at my own laptop's IPCONFIG.....it listed the same type of protocol that you found to be unusual in my daughter's laptop...Tunnel Adapter Teredo Tunneling Pseudo-Interface. I use linksys as my router and had gone to their website to automatically configure my laptop as it was connected to the router. I did the same with my daughter's. I wonder if that is where that configuration came from.

Will.Spencer · 10-25-2006, 07:26 PM

To delete a connection:

Click the <Start> button
Click the <Control Panel> menu item
Click the <Network Connections> icon
Highlight your network connection icon
Press the <DELETE> key
Click the <Yes> button

I'm using a LinkSys WAP here and was using a LinkSys wireless NIC and don't have either IPv6 or Teredo. I dunno.

i cant conect to the internet. i have a wireless connection and its not connecting. idk wats wrong with it but its not connecting. repairng doesnt work. help?

Will.Spencer · 11-16-2006, 07:07 PM

When you view wireless networks, do you see your network?

If so, what signal strength does it show?

Do you receive any error messages when you attempt to repair the connection?
