Limited or no connectivity is one of the worst errors that can affect the internet accessibility. In general this particular error code can be generated due to several reasons to name a few of them would be:
(A) System Issue
(B) Networking card (PCI or PCMCIA card) driver incompatibility.
(C) ISP (Internet Service Provider) problem.
Among the above mentioned cases system issue is the most complicated one as it becomes completely related to the operating system (Windows XP or Vista). Where in a few steps can be followed as:
a) Power cycle (Restart) the router -- click on “START” and “RUN” -- Type in “cmd” in the run box (This opens up the command prompt or the DOS shell).
b) In the DOS shell type in “IPCONFIG /RELEASE” in lower case the IP address would come down as “0.0.0.0”. Followed by that again in the same DOS shell type in “IPCONFIG /RENEW”. Close the DOS shell and check if you are able to go online or not. If “YES” then it’s alright.
If “NO” then follow the advanced troubleshooting steps provided below:
c) Sometimes even putting in a “STATIC IP” also helps. Like click on “START”
-- “Connect to” -- “Show all connection” -- select LAN or high speed internet/wireless whichever is applicable (Right click on the icon and select PROPERTIES) -- select Internet Protocol (TCP/IP) IPv4 or IPv6 -- click on PROPERTIES button -- put in the static IP’s in the format given below in the screenshot(keeping in view your router IP coverage by the router).
Check if with this step the issue gets resolved or not.
Even if this does not help then we can try out with another step.
d) The next turn around for the situation can be done by resetting the TCP/IP stack altogether which can be done by clicking on “START” -- “RUN” -- “cmd” -- in the command prompt the following code can be typed out ie, “netsh int ip reset c:\resetlog.txt” -- Restart the computer/laptop (The following above step is only valid for Windows XP Service Pack 2&3).
If this too does not solve the issue then second basic point comes into the scenario where the “NETWORK CARD” (PCI or PCMCIA card) either internal or external (eg: Belkin USB adapter) driver might have gone corrupted. The turn around for the same would be to install the drivers afresh from the CD/DVD received while the purchase of the card or as a update from the vendor website or one taken from the local computer vendor. Once the updates are done access the network card from “START”-- “Connect to” -- “Show all connection”-- select LAN or high speed internet/wireless whichever is applicable--right click on it and “DISABLE” the card--followed by that again “ENABLE” the card and check if now it takes you online or not.
If the issue still persists then have a word with your ISP if there is any problem in and within the service they are providing as the issue would get automatically resolved when the outage in your area would be rectified within your area.
