    Ok, recently my computer and internet was working just fine until last night. MY computer just didnt connect. So i called dell and they just fixed it right now by going into my router settings and changing a few things like changing my security to WPA Personal from WAP Open. Before I was usually getting full bars with excellent and good signal strength, but now after I fixed my internet problem, my signal strength is at poor. I tried restarting the computer but it did not work. What should I do? How can I fix it? Also, I have 2 antennas from my wireless computer and they are both parallel from the floor.

    10 tips for improving your wireless network

    10 tips for improving your wireless network

    If Windows ever notifies you about a weak signal, it probably means your connection isn't as fast or as reliable as it could be. Worse, you might lose your connection entirely in some parts of your home. If you're looking to improve the signal for your wireless network, try some of these tips for extending your wireless range and improving your wireless network performance.
    [​IMG]1. Position your wireless router (or wireless access point) in a central location

    When possible, place your wireless router in a central location in your home. If your wireless router is against an outside wall of your home, the signal will be weak on the other side of your home. Don't worry if you can't move your wireless router, because there are many other ways to improve your connection.

    2. Move the router off the floor and away from walls and metal objects (such as metal file cabinets)

    Metal, walls, and floors will interfere with your router's wireless signals. The closer your router is to these obstructions, the more severe the interference, and the weaker your connection will be.

    3. Replace your router's antenna

    The antennas supplied with your router are designed to be omni-directional, meaning they broadcast in all directions around the router. If your router is near an outside wall, half of the wireless signals will be sent outside your home, and much of your router's power will be wasted. Most routers don't allow you to increase the power output, but you can make better use of the power. Upgrade to a hi-gain antenna that focuses the wireless signals only one direction. You can aim the signal in the direction you need it most.

    4. Replace your computer's wireless network adapter

    Wireless network signals must be sent both to and from your computer. Sometimes, your router can broadcast strongly enough to reach your computer, but your computer can't send signals back to your router. To improve this, replace your laptop's PC card-based wireless network adapter with a USB network adapter that uses an external antenna. In particular, consider the Hawking Hi-Gain Wireless USB network adapter, which adds an external, hi-gain antenna to your computer and can significantly improve your range.
    Laptops with built-in wireless typically have excellent antennas and don't need to have their network adapters upgraded.

    [​IMG]5. Add a wireless repeater

    Wireless repeaters extend your wireless network range without requiring you to add any wiring. Just place the wireless repeater halfway between your wireless access point and your computer, and you'll get an instant boost to your wireless signal strength. Check out the wireless repeaters from ViewSonic, D-Link, Linksys, and Buffalo Technology.

    [​IMG]6. Change your wireless channel

    Wireless routers can broadcast on several different channels, similar to the way radio stations use different channels. In the United States and Canada, these channels are 1, 6, and 11. Just like you'll sometimes hear interference on one radio station while another is perfectly clear, sometimes one wireless channel is clearer than others. Try changing your wireless router's channel through your router's configuration page to see if your signal strength improves. You don't need to change your computer's configuration, because it'll automatically detect the new channel.

    7. Reduce wireless interference

    If you have cordless phones or other wireless electronics in your home, your computer might not be able to "hear" your router over the noise from the other wireless devices. To quiet the noise, avoid wireless electronics that use the 2.4GHz frequency. Instead, look for cordless phones that use the 5.8GHz or 900MHz frequencies.

    8. Update your firmware or your network adapter driver

    Router manufacturers regularly make free improvements to their routers. Sometimes, these improvements increase performance. To get the latest firmware updates for your router, visit your router manufacturer's Web site.
    Similarly, network adapter vendors occasionally update the software that Windows uses to communicate with your network adapter, known as the driver. These updates typically improve performance and reliability. To get the driver updates, do the following:
    Windows 7 and Windows Vista


    • Click Start menu, click All Programs, and then click Windows Update.
    • In the left pane, click Check for updates, and then wait while Windows Vista looks for the latest updates for your computer.
    • Install any updates relating to your wireless network adapter.

    Windows XP


    • Visit Microsoft Update, click Custom, and then wait while Windows XP looks for the latest updates for your computer.
    • Install any updates relating to your wireless adapter.



    9. Pick equipment from a single vendor

    While a Linksys router will work with a D-Link network adapter, you often get better performance if you pick a router and network adapter from the same vendor. Some vendors offer a performance boost of up to twice the performance when you choose their hardware: Linksys has the SpeedBooster technology, and D-Link has the 108G enhancement.

    10. Upgrade 802.11b devices to 802.11g

    802.11b is the most common type of wireless network, but 802.11g is about five times faster. 802.11g is backward-compatible with 802.11b, so you can still use any 802.11b equipment that you have. If you're using 802.11b and you're unhappy with the performance, consider replacing your router and network adapters with 802.11g-compatible equipment. If you're buying new equipment, definitely choose 802.11g.
    Wireless networks never reach the theoretical bandwidth limits. 802.11b networks typically get 2-5Mbps. 802.11g is usually in the 13-23Mbps range. Belkin's Pre-N equipment has been measured at 37-42Mbps.

    That is all very good advice. /From https://www.microsoft.com/athome/setup/wirelesstips.aspx)

    But, if your connection was working OK, and you suddenly lost it, I would suspect other problems.
    Did you manually knock the router or the antenna?
    If not, see if you are not accidentally connecting to e neighbours gear.
    Click the icon in the noytification area and see if any other connections are available. If so, that could be where the problem is. Make sure you are on the correct router.
    One quick test, so simple, for router problems, is to bypass it.
    Bring your cable from the router, direct to your computer ethernet connector. Make sure your ethernet adapter is operational and see what kind of a signal you are now getting. If it is normal strengh, then it is back to an examination of the router. Post back what make it is. Do you alread.perhaps, know how to access the firmware?
