OnePlus 5T review: Hands-on
for the last three days i have been unable to get onto my broadband account thru BT. I use a linksys modem, and router; both of which diagnose themselves as working fine. BT can see my connection from their end so the connection is fine. i suspect the problem is the linksys system as my laptop cant get online either thru the wi fi set up.
now the tech bit. when i try to go online thru internet explorer or outlook or msn, all are denied. when i go to control panel/network connections/ and try to Repair the connection it stops repairing at "Can not clear DNS cache" . when i enter the run cmd of ipconfig /flushdns as has been advised to me by the pcadvisor helpline it comes up with the statement that dnscache flush could not be executable and doesnt clear it.
so, ultimately what on earth is the dnscache, could it be the reason why my internet connection has gone dead? how can i flush it? the irony is that the microsoft knowledge base that is directly related to this issue is not available at the moment!!!!( last reviewed september 2004!!!!!)
i recently upgraded to norton internet security 2006 from 2004; but it worked perfectly for a week before the connection went dead... so im not sure if it could be a problem.. i know that norton has a learning feature for its firewall and maybe it learned itself to close some ports that were important?? i would be reluctant to uninstall norton having paid 50 quid to download it in the first place.
any suggestions or ideas or comments no matter how trivial??
Renewing Your DHCP-Assigned IP Address
Sometimes, while assigned an IP address by a DHCP server, your PC doesn't appear to be on the network and you can't get Internet or network access. Renewing your IP address often solves the problem.
If you're on a network but you can't send or receive data, use any network resources, or visit the Internet, the culprit may be a problem with your DHCP-assigned IP address. The simplest way to fix it is to renew the IP address—get rid of the old one, and ask the DHCP server to send along a new one.
Before trying this, first make sure you're using a DHCP-assigned IP address rather than a static one. Right-click on My Network places and choose Properties to get to the Network Connections folder. Right-click on your current network connection and choose Properties. On the General tab, select Internet Protocol (TCP/IP) and choose Properties. On the General tab, the radio button next to "Obtain an IP address automatically" will be selected if you're using DHCP.
After you've confirmed you're using DHCP, release your current IP address by typing ipconfig /release at a command prompt. The ipconfig command is an all-purpose command that lets you solve many network-related problems. To renew the address and get a new IP address from the DHCP server, type ipconfig /renew at a command prompt. Your new IP address should fix the problem.
To find your new IP address, type ipconfig at a command prompt. You can also select your connection in the Network Connections folder, click on "View status of this connection," and click on the Support tab, which shows your new IP address and confirms that it was assigned by a DHCP server.
Repair a Broken TCP/IP Connection
TCP/IP problems can be exceedingly difficult to troubleshoot, and at times they appear to break for no apparent reason. Everything looks like it should be working, but you're not able to connect using the protocols. If you have a broken connection, try the following:
Try automated repair. Right-click on the broken connection in the Network Connections folder and choose Repair.
Run the Network Setup Wizard. It walks you step by step through TCP/IP and network configuration and will correct any errors you may have introduced inadvertently.
Reset your router. If you have a home network, the problem may lie with the router or in the connection between the router and your broadband provider. Follow the directions for resetting the router.
Reset your cable modem or DSL modem. If you have a broadband connection, the problem may lie in the assignment of your IP address by your ISP. Power off your cable modem or DSL modem, unplug its Ethernet cable, and leave it powered off for five minutes. Then restart it. This is also a good time to reset your router. You can also try releasing and renewing after you've turned the connection back on.
Reset TCP/IP to its original configuration. If all else fails, you can try to reset your TCP/IP stack to the same state that it was in when XP was first installed on the computer. Use the NetShell utility. Issue this command: netsh int ip reset [log_file_name], where log_file_name is the name of a file where the actions taken by NetShell will be recorded.
thanks a million 4 sorting out my simlar prob
enter this at the command prompt and it might help.
Make sure the dns client is running in local services.If it isnt select auto when enabling it
