Question about Toshiba Satellite L675D-S7100 Notebook PC

1 Answer

Toshiba satellite L675D-S7100 will not stay connected to AT&T UVERSE wi-fi

I previously had AT&T DSL internet service and had no connection issues, other than the fact that 3MB DSL is useless. I just had the service switched to 6MB AT&T UVERSE and my laptop constantly loses wi-fi connection. It will connect, almost immediately disconnect, then connect again over and over. Cell phones and wireless DVR for TV do not seem to have a problem with the wi-fi staying connected.

    Windows 7 seems to be the culprit here.. If you are reading this and you have the same type problem with UVERSE and are using Windows 7. AT&Ti is not going to help. They are going to tell you that there is something wrong with your computer. That's just not the case. Most likely you are on the same default wireless channel as all your neighbors and it might help to change this. Just search (inSSIDer) download their program and you can see what channel the nearby networks are using. I did this, but what I believe actually solved my wi-fi connection problem was changing the security authentication from (TKIP) to (AES). Windows 7 does not seem to like the default TKIP security. It is constantly trying to verify and therefore loses the connection. I changed mine to (AES) and I have had no connection problems since then. Both of these settings are changed from the 2WIRE device configuration page. To get here you must look at the label on the side of your modem. In small print it says "for advanced configuration go to" now type the numbers you see into your search bar. (assuming you have connection long enough to do this. If not connect via ethernet cable) Now, from this page look to the bottom where it says (Top Networking Features) and click on wireless. Here you can change both setting I mentioned. When you attempt to modify any settings it will ask you for a system password. It is not the password you use to connect to your wireless. (WEP KEY on side of modem) The password for this page is on the power pack to your UVERSE system. It is the big AT&T box they installed probably in your garage that is plugged into an outlet. Type the system password in and you may now change and save your new settings. I can not say that this will work for any other problems or different versions of Windows. I only know this worked for me in my situation using Windows 7. One more thing, from what I understand, the best wireless channels to use are 1, 6, 11. Majority of my nearby networks were on channel 1. I switched to 11 and get better signal strength.

    AT&T tech was just here.. he is trying to tell me that because his ipad connects that the problem must be my laptop. and then informs me that since he doesn't know what the problem is and is convinced it must be my computer that I am going to be billed $100 for the service call.. I would love to know how or why my computer became the problem between working fine on DSL and switching to UVERSE. Especially since there are pages and pages online about people having the same problem after switching to UVERSE

Is it possible to connect a standard DSL modem - without Wi-Fi (with 1 Ethernet port) and a DSL modem - Wi-Fi (with 4 Ethernet port) to broadcast Wi-Fi singles

Does the non wifi modem give out DHCP addresses?
Can the wifi modem be set up to receive it's IP address from DHCP?
If the answer to both these questions is Yes then that's what to do as a first step. Make sure the wifi modem DHCP service is disabled as it must NOT give out DHCP addresses.
Connect the ethernet port of the non wifi modem to one of the LAN ports of the wifi modem and NOT the DSL/WAN port. The wifi modem is not participating in any DSL connectivity at all so it's DSL light will remain off. The non wifi modem is doing the DSL duty so it's DSL light should be correctly illuminated.

Wii Error Code 91010.

Error Code: 91010
Our experience shows that error messages within this range are typically caused by temporary network issues with the Nintendo Wi-Fi Connection. If there is a problem with the network, our technicians will work to get the service back up as soon as possible. Please retry your connection later.
If you are connecting to the Nintendo Wi-Fi Connection for the first time, or the problem has not resolved itself after a few hours, please review the following:
  1. Our servers may be trying to handle an unusually high amount of traffic (especially if you are trying to play online with a recently-released or popular game, or if there is a new Wii system update). Please wait a few hours and try the connection again later.
  2. How are you connecting online? The Nintendo Wi-Fi Connection is only compatible with Cable, DSL, and Fiber-optic internet connections. If you are connecting via Satellite, EV-DO (cellular), Dial-up, or other types of connections, then you should try to use an alternate type of connection. Contact your Internet Service Provider if you are not sure what type of internet connection you have.
  3. The error may be caused by a basic setting on the router that needs to be adjusted (such as the channel). Please review our general router troubleshooting.
