DNS Server

[kshook2009]

Hey everyone, I have a Sony Vaio VGN-FW 351J laptop, every since I upgradded to seven, when i connect to my router (D-link DIR-628) I will have a internet connection for lets say 20 min, after that, my internet connection on the tool bar gets the yellow notice sign and my computer is still connected to my router but than i dont have internet access? I run the diagonstic tool and before it is done, my internet returns, but than it happens again, I once got the diagnostic tool to finish and it said something about a DNS server.. .Anyone help??


BTW, when other laptops connect it dosent do this

You mean maybe DHCP server?

Set the lease time on the router to its maxiimum setting - usually 99 days.

Alternatively and better, set a static ip address for the adapter in Windows.

Also, change the wireless channel you're using and set beacon interval = 500 ms.

Let us know if you have mdnsresponder.exe in the task manager.

Unless the laptop is not going to connect to another router (coffee shop, book store), setting it up for static IP is not the way to go.

That's the reason I didn't suggest it first.

DHCP Lease time? if so, thats already set at 1440,

to set static ip, how to I get the ip of my internet provider?

Is beacon period the same? if so mine is set to 100

 

[torrentg]

Set beacon period = 500 ms. Yes, same.

If you want to set static ip, you don't need any info from ISP. Use the router's config page address for default gateway, subnet mask = 255.255.255.0.

Ip address = same as router's config page only change the last part to .150

For preferred dns server, use 208.67.222.222

As the Pc can still see the router but not the internet I think that this could be a DNS issue rather than DHCP.

One other thing It may be is a time-out setting in the router which is there to keep costs down on the old type Pay to connect rather than always on ISP deal - check in the router's settings for something like disconnect after 20 minutes ... or similar

To check if this is a DNS issue you could try changing your DNS Servers an example is ...

Primary 8.8.8.8
Secondary 8.8.4.4

Set these in the DNS setting of either your Network adaptor settings or Router

 

[kshook2009]

Their is no time-out setting,

Diagnostic tool says DNS Not responding

 

[torrentg]

Did you try changing the radio channel to something different on the router?

 

[kshook2009]

well its 2.4ghz and a 5ghz router, when i run it on 5ghz my computer is the only one able to pick up the signal?

but I have reset the router before to factory defasults but still dosent seeem to help

 

[torrentg]

Those are available frequency ranges. Try setting a different channel while using 2.4 then.

US = 1 -11 available
Europe = 1 - 13 available

(Depends on firmware)

 

[Barman58]

One other thing to check - if this is an older router - check if there is a firmware update available from D-Link - there were changes to the Network stack between XP and Vista and minor changes between Vista and win7 - an upgrade to the latest firmware may correct the drop outs

 

[kshook2009]

Changed it to 2.463 Ch-11 well see what happens,

its a brand new router... I think maybe the newest one dlink makes?

Doesn't mean there isn't a firmware update.

 

[Barman58]

One thing that did cause time-out problems on some routers with Vista was the “Receive Window Auto-Tuning”

Switching this off cured the issues in many cases - This tuning is still used in win7

Commands need to be run in an elevated command prompt

Switch off

netsh interface tcp set global autotuninglevel=disabled

Switch On

netsh interface tcp set global autotuninglevel=normal

Display Settings

netsh interface tcp show global
