Wireless Issues

Hello,

I'm using a Sony Vaio VGN-NR280E laptop, running Windows Vista, using a D-Link router, network is not encrypted, and also running Avast! Antivirus. My laptop suddenly can't connect to my wireless network immediately. It takes about 1/2 hour before it connects. But after resuming from suspend, hibernation, or restarting the process just repeats itself.

A little back story: I was out of town for the weekend and was using the wireless at the motel that I was staying at, everything worked fine. I come home and the wireless should, after a minute, connect, instead it just keeps telling me it's not connected. After waiting for about 1/2 an hour the connection works fine and doesn't drop once I am connected. Also, "Obtain an IP address automatically and Obtain DNS server address automatically" are both selected.

I've tried:

Restarting - have to wait about 1/2 hr or so before I am connected
Virus check - no viruses
Spy bot check - nothing detected
Drivers - Intel Wireless Driver up-to-date
Wireless Lan switch - On and light is green

It detects the wireless network, but fails to connect. Also diagnosed the issue and came up with "try connecting to another network/troubleshoot when wireless signal is low." The troubleshooting FAQ didn't work. Why is it taking so long to connect to the network now? I'm not very computer saavy so I'm at a loss as to what to do next.

I'd be grateful for your help. Thanks.

That tells the DHCP server to reassign your computer an IP address.
The flushdns command tells your computer to delete what the DNS has cached.

This is safe, and please post the results.

Okay, I waited about 15 minutes before I could connect to the network. I also tried doing it while offline but didn't get anything back. So here are the results:



ipconfig/ release

Error: unrecognized or incomplete command line.

USAGE:
ipconfig [/allcompartments] [/? | /all |
/renew [adapter] | /release [adapter] |
/renew6 [adapter] | /release6 [adapter] |
/flushdns | /displaydns | /registerdns |
/showclassid adapter |
/setclassid adapter [classid] ]

where
adapter Connection name
(wildcard characters * and ? allowed, see examples)

Options:
/? Display this help message
/all Display full configuration information.
/allcompartments Display information for all compartments.
/release Release the IPv4 address for the specified adapter.
/release6 Release the IPv6 address for the specified adapter.
/renew Renew the IPv4 address for the specified adapter.
/renew6 Renew the IPv6 address for the specified adapter.
/flushdns Purges the DNS Resolver cache.
/registerdns Refreshes all DHCP leases and re-registers DNS names
/displaydns Display the contents of the DNS Resolver Cache.
/showclassid Displays all the dhcp class IDs allowed for adapter.
/setclassid Modifies the dhcp class id.

The default is to display only the IP address, subnet mask and
default gateway for each adapter bound to TCP/IP.

For Release and Renew, if no adapter name is specified, then the IP address
leases for all adapters bound to TCP/IP will be released or renewed.

For Setclassid, if no ClassId is specified, then the ClassId is removed.

Examples:
> ipconfig ... Show information
> ipconfig /all ... Show detailed information
> ipconfig /renew ... renew all adapters
> ipconfig /renew EL* ... renew any connection that has its
name starting with EL
> ipconfig /release *Con* ... release all matching connections,
eg. "Local Area Connection 1" or
"Local Area Connection 2"
> ipconfig /allcompartments ... Show information about all
compartments
> ipconfig /allcompartments /all ... Show detailed information about all
compartments

ipconfig /renew

Hi

ipconfig/ release

Error: unrecognized or incomplete command line.


The reason you received this is because you didn't have a space between the g / correct command is
"ipconfig /release"

with that corrected please repeat these commands:

ipconfig /release
ipconfig /renew
ipconfig /flushdns

That should do it for you

Good luck

just saw the problem quick figured I would get it resolved for you for next time your back on

I see that error now. But I tried again with the correct command and it came up with "The requested operation requires elevation."

FYI, I plugged my laptop directly into my router using an ethernet cord, but only after a few tries. Then, I logged into my router to make sure everything was functional and that the network settings matched the router settings. Everything looked the same. I have a PC downstairs and it's working fine, no problems with connecting to the internet whatsoever.

A funny thing is happening as I am typing this reply. I keep getting disconnected, while using the ethernet cord, and next to the dlink network it now says, "the settings saved on this computer for the network do not match the requirements of the network". That wasn't there before?? I can connect via the ethernet cord, but the wireless still isn't picking up the network and apparently my settings aren't matched. :)

I really have no clue what's wrong. Any other ideas??

I'm actually leaning towards a System Restore, because I can't figure out what's wrong with it.

However, I talked to a Sony Rep. and that person told me to remove the network from my list. I tried connecting again, but I totally forgot the password/passphrase. But it's supposed to be unencrypted so I don't know why it's prompting me for a PW?

So I still have to contact DLink about that. I've removed the network, but if I reset the router to factory settings before trying a system restore, will it revert back to an unencrypted network?

Thank you cbarnard for the assist.

Follow the instructions in the link to get past the "Opertaion requires elevation"

So I still have to contact DLink about that. I've removed the network, but if I reset the router to factory settings before trying a system restore, will it revert back to an unencrypted network?


It should return to an unencrypted network if you reset the settings.

You might want to do a system restore to the earliest date you can find. This may fix the issue.
