Question about Computers & Internet

My computer doesn't see wireless networks any more. I know there are networks because I have tried it in 2 different locations where we have wireless networks. It hasn't been disabled in network connections. I have also tried to get windows to repair the connection but it hasn't worked. Any ideas?

2. Analogue video senders used to send audio and video to other TVs in the home.
3. Microwave ovens emit interference in the 2.4GHz band.
4. Wireless speakers and console controllers can cause interference with the wireless router.
5. Bluetooth devices, newer Bluetooth devices can jump to different frequencies if there is a connection problem.

8. Depending upon the location of large mirrors will reflect wireless signal away your computer.
9. Building materials will block wireless signals such as plasterboards with metal foil, reinforced concrete walls and floors. Also objects near the wireless router such as metal filing cabinets and other electrical appliances.

Computer doesn"t start keep rebooting


Try moving the card to a different slot.
Swap slots with another card if all the slots are full.
If this doesn't work, post a reply / add a comment to this post and I'll dig deeper for more options, but in most cases like this, using a different slot or swapping slots with another card will most often fix the issue.

Reset bridge to different router without the disk.


Follow these steps :
•1
Reset the bridge. Accomplish this by manually disconnecting the power source from the wall or the back of the bridge. Leave it disconnected for 30 seconds to a minute so that the software contained therein can fully reset. Reconnect the bridge and wait two to three minutes until the network is back up and running again. In many cases, a simple reset can solve your network-related bridge problems.
•2
Ascertain whether there is network activity on your computers. Accomplish this by looking at the back of each computer at the network card. There should be two lights next to your Ethernet port--at least one of these lights should be completely lit without flickering. This indicates that the network card in the machine is operational and ready to receive a signal, eliminating that as a possible problem source.
•3
Move the bridge to a different location to determine whether interference is preventing the network computers from receiving a proper signal. If possible, relocate the bridge to the same room in which the computers are located and try to reset the connection again.
•4
Determine whether the bridge has failed altogether or whether the wireless signal from the bridge has failed. Accomplish this by physically connecting the computers to the wireless bridge through the use of Ethernet cables. If this restores network connectivity, you know that the only problem with the bridge is the wireless signal emission.

Why does the linksys wireless router ''WirelessG: keep going off/



Intermittent Connectivity:
NOTE: Before following the steps in this article, check if your wireless computers have stable connection when connected to other wireless networks (hotspots).
This article assumes that all wireless computers are experiencing intermittent wireless connection with the Linksys router.
Frequent wireless disconnection can be caused by different factors such as:
  1. Wireless interference within the network.
  2. Wireless settings of the Linksys router are still set to default.
  3. Firmware is corrupted.
Reducing Wireless Interference
If you are experiencing frequent disconnection from the wireless network, it helps if you check the following factors, all of which can greatly affect your wireless signals:
your cordless telephone system (or even your neighbors’), or other nearby equipment. Try to change your router’s channel to 1 or 11 (the default channel is 6) and restart the wireless computers.
Physical obstructions: Your router or wireless computers may be losing connectivity because of physical obstacles such as walls and floors. Try to move the equipment to different locations to find a better link.

  • Placement of the router: Linksys suggests that you place your router as high off the ground as possible. When placing the router in a high location, leave a distance of two feet between the router antenna tips, ceiling, and wall. If your signal passes through multiple floors, place the router on the upper-most floor, and high up in the room.
  • Surroundings: Keep the router away from large metal objects, bodies of water (fish tanks, bathrooms), and any electrical equipment including television sets, microwaves, radios, etc.
Customizing Wireless Settings of the Router
Having default wireless settings on the Linksys router may cause conflict with other Linksys routers within your network range. Linksys suggests changing the SSID (network name) and the Wireless Channel of your router. Also, if it is possible, enable the Wireless Security of your router.
To change the router’s SSID or the wireless network’s name, click here.
To change the router’s channel, click here.
To enable the wireless security on the router, click here.
NOTE: If the wireless connection remains unstable after performing the steps above, upgrade the router’s firmware. For instructions, click here

If I could be of further assistance, let me know. If this helps or solves the issue, please rate it.

Verify the wireless network power switch is on. The wireless network device in the computer can be turned on and off. The network power switch is located in different places on different computers. See the User Guide for the location on your model. Most models have a blue LED c01481711.jpg that glows when the wireless network switch is on Verify the wireless network connection is enabled The connection to a wired or wireless network can be disabled or enabled. To verify the status:
  1. Right-click the Network Connection icon c00814097.gif in the system tray, and select Network and Sharing Center .
  2. Select Manage network connections .
  3. Verify the status of the wireless network. c01481714.gif In this graphic, the wireless network is disabled.

Adapter see the network but don't connect. No error messages


Hmm... well, generally USB 2 devices are backwards compatible, so you should be ok there. I would suggest that you start with checking the network settings on all of the devices. My guess is that you have the devices on different subnets. I found a procedure on the subject that can walk you through the process of checking the network settings on your computers too... http://us4.samba.org/samba/docs/man/Samba-HOWTO-Collection/ClientConfig.html. Make sure that each of them are set to DHCP so that the router can automagically assign the right addresses. You may also need to look at the router configuration to ensure that wireless is enabled and that the settings match... like Wireless Encryption (WEP) keys, etc. If that doesn't solve your problem, let us know and we can go deeper into diagnostics.
