    Trouble with home wireless network


    I recently upgraded to Windows 8 and am having trouble connecting to my home network.

    I have a Motorola Wireless Cable Modem Gateway SBG900.

    1. My iPhone can connect to the network just fine.
    2. I tried reentering the password in Windows, but that did not work.
    3. I also tried restarting the router for 10 seconds, but that did not work.
    4. I can connect to the wireless network at work without any trouble.
    5. I connect to the modem via ethernet and the internet worked fine.

    Any thoughts? Thanks.

    If other devices can connect then it is more than likely the wireless security settings on your failing device.

    Bottom right hand side of the screen near the time and date right click the wireless symbol and open up the network and sharing centre.

    Choose manage wireless networks located top left of page this takes you to your security profile for your wireless card. Right click and goto properties and then chose the security tab.

    Check your security type, encryption method and password matches the details on your router.

    If in doubt best to delete the current network profile from the problematic machine and manually create one to be doubly sure nothing is corrupted.

    Hope this helps

    This problem could be because most drivers for Windows 8 wireless NIC's are not made to connect with the very outdated WEP security which is what your surfboard modem/router is using.

    No doubt the wireless A/P at your work is using more modern security such as WPA2 and AES encryption. It may help to define the settings in for the wireless profile as suggested earlier.

    You are correct. I am using WEP, which apparently is not supported by Windows 8. I tried to follow Andy's advice and that also did not work. How do I define the settings so that it will recognize the Morotola Surfboard? Or do I just have to purchase a new cable modem?

    I would update the cable modem to one with 802.11n "4 times faster than G" and supports the newer security protocols.

    I'm not sure what your ISP will provide you with but ideally you would should use regular modem then plug that into a third party router of some type, D-Link, Netgear, Linksys etc.

    I use the same modem in line with an older d-link DIR-615 router. This model (SBG900) is not an all in one where you can plug in multiple devices so the author has to have some kind of router already there. Go into the router settings and see if you can change the security to WPA or WPA2. I have 2 win8 and one win7 machines networked and they work fine.

    The SBG900 does have WEP or WPA (no WPA2) but you need to go into the setup to change it. I don't know what the default is set to because mine worked correctly right out of the box. Again I think the problem is in his router, assuming he has more than one PC networked.

    The model in question here has a wireless access point so it is in fact a modem/router, should handle 252 connections. If it has WPA then it should be used but you will still be limited to wireless G speeds of only 54Mbps.

    The default setting using WEP security was no doubt the cause of the problem as I pointed out earlier but for some reason the specs only list the lousy WEP security and slow wireless G speeds which Windows 8 really isn't made for.

    Try to remember that these units are usually free with the cable subscription and it doesn't cost anything to upgrade to a newer Modem only model, like the one I'm using now which is the SB5101 surfboard cable modem. Amazon.com: Motorola Surfboard SB5101 Cable Modem: Electronics

    I suggested using a router that supported 802.11n or even the new 802.11ac just because it's potentially so much faster than wireless G, combining a standard modem with a modern router would show the best results here.

    From the instruction manual:

    Connect your computer to the SBG900 SURFboard using an RJ-45 cable connected between the computer's LAN port and the SURFboard LAN port. Motorola does not recommend configuring the wireless interface while connected wirelessly.

    2. Open your Web browser and navigate to "http://192.168.100.1" or "http://192.168.0.1" to bring you to the SBG900 SURFboard login screen. The default user name is "admin" and the default password is "motorola." Both fields are case-sensitive. Substitute your own password if you created one during the initial set up.

    3. Click the "Wireless" button on the left hand side of the screen. Click the tab labeled "Security" to get to the wireless securitybasic setup screen.

    4. Click the WPA radio button. There is an option for WEP, but WPA is far more secure. If you have an older device that does not support WPA, select WEP instead. The set up process is the same except for choosing the type of encryption to use.

    5. Select AES WPA type encryption in the security mode section on the "Security" tab. Motorola recommends using AES over TKIP because TKIP can perform slowly. TKIP is available for legacy support, but nearly all devices that support WPA also support AES encryption.

    6. Type a password or passphrase in the "PSK-Passphrase" field. The password or
    passphrase must be between 8-63 characters. Press "Save Changes" when complete. If you chose WEP instead of WPA, type an 8-31 character password or passphrase in the "WEP-Passphrase" field. Click the "Generate WEP Keys" button. Click the "Enable 128-Bit" radio button and then click "Save Changes."

    +++++++++++++++++++++++++++++++++

    I think all he needs to do is get to the security page and tick the WPA button, choose the AES encryption and save. Reboot the modem first and then the computer to be safe and see if it works.

    GOOD LUCK!

    If you do decide to replace your equipment as chev65 recommended make sure it is ipv6 certified. Windows 8 does not play nice in a mixed OS environment. My Windows 7 computer can "see" and hook up to my shares and printers on the Windows 8 computers but not so good the other way around. The printer and shares on the Windows 7 computer come and go at random and I suspect it is because the older D-link DR-615 is ipv4 only.

    Edit

    The only way I can insure a consistent hook up to my Windows 7 computer shares and printer from either Windows 8 computer is to map a drive to one of the windows 7 shared folders and have it to hook up at start up. Make no sense to me but if I don't keep one of the shares mapped the Windows 8 computers either fail to hook up to my shares and printer OR they drop out and come back at random. Crazy.
