Answer 1

What is happening is you are using wifi coneection to the internet and the most probable cause of your disconnection will be down to another wifi router in the area working on the same channel as yours.



You're most likely suffering from what they call cross-talk, when two devices try to work on the same channel in the same area. As their signal takes precedence your one gets dropped and vice-versa.



To fix this you need to hook up your modem/router to your computer using a LAN cable and access its config page. Change the default channel to something different (e.g. if its on ch.9 change it to 11 or 13.)



Some routers can auto set the channel so a quick fix might just be to switch it off then back on.



Hope this helps :)

1. IPConfig is a tool built into Windows,that displays all current TCP/IP network configuration values and refreshes Dynamic Host Configuration Protocol DHCP and Domain Name System DNS settings. You can access this tool via the command line. If you have a bad IP address, then renewing your IP address this way may help solve your internet problems.



Type cmd in start search and press Ctrl-Shift-Enter. If you wish, just out of curiosity, you may type ipconfig and hit Enter, to view the status of the computer’s Internet Protocol or IP address.



Type ipconfig /release to let go of the current IP address.



Next type ipconfig /renew to obtain a new IP address.



You may get an error Message When You Run the “Ipconfig /Renew”



If you recurrently face this problem, then you can have it renewed on every start-up, by creating the following .bat file and placing it in your startup folder.



Open notepad and type:



ipconfig /release

ipconfig /renew



Save it as, say, iprenew.bat file.



2. Frequently, internet connection problems can also be traced to a corrupted DNS cache. Resetting or Flushing this cache is an easy fix to many of these problems. This is how to clear the DNS cache in Windows 7 or Vista.



Start > All Programs > Accessories > Command Prompt. Right click on it and ‘Run As Administrator’. Type the following and hit enter:



ipconfig /flushdns



You should be able to see a confirmation dialog window:



Windows IP Configuration. Successfully flushed the DNS Resolver Cache.



Next type ipconfig /registerdns and hit Enter.



This registers any DNS records that you or some programs may have recorded in your Hosts file.



Just in case you are interested, to view the complete syntax for this command type ipconfig /help and hit Enter!



3. The Network & Internet Diagnostic & Repair Tool in Windows 7 & Vista will help you identify the potential issues preventing network connectivity, and it automatically takes appropriate steps toward correcting them. If a computer on the network loses Internet connectivity, you can graphically see which connection is down and then use Network Diagnostics to help determine the cause of the problem and find possible solutions.



network & internet



To access it, open Control Panel > Network & Sharing Center. In the lower part, click on Troubleshoot Problems. From the windows which opens, you can select Internet Connections or any other issue you want to troubleshoot and repair.



Hope this solves it for you

1- Do you have wireless phone? check the freq. of your phone vs your wireless card. If same range move your phone or router to a different location. or disconnect your wireless phone during testing. 2- try a different channel on your router and card (they must match). 3- Look at available wireless networks if any strong signals with same channel switch yours. 4- upgrade or reflash your router. 5- Try another wireless card (usb) and see if it works 6- make sure your router supports your cards band (B,G,N)
