On my windows vista dell laptop it say limited acess to linksys

If you are saying like 5 devices? Wonder if your internet provider ia allowing that? Sometimes they do have a limit and if you go over that it will lock up or fail...lose signal. Not saying you are doing something bad but maybe you do have a limit of devices allowed. If this is the problem leave one device off or switch off if not needed.

Have you had a look on the firewall website for a suitable firewall system that compliments windows 7?
I had to download a new one myself when I went from Windows XP to Windows Vista.

Sometimes changing systems means you should also change your firewall, then you'll have the most up-to-date software going. Plus it won't slow your computer down like it doesn't sometimes.
Hope I helped Dr Reed

For that you need to enable DHCP in router .
Connect your router to computer with ethernet cable.
then you can access it with default link
http://192.168.1.1
or
http://192.168.0.1
type user as "admin" and password as "admin" or blank or "password"
Then you can see configuration page of router.
Then enable DHCP.
then save all settings and restart router.
Then set in your lan card adapter property ip get automatic.
Let me know if you need further assistance.
thanks for using FixYa.

first of all turn your antivirus and firewall back on at once, as this is not the cause! i think this may be some cable modem<->vista incompatibility

Start off simple. Try a different port on the router. If that doesn't work, try a new cable. If that doesn't work, go to the Device Manager in Windows. (Right-click My Computer, select Manage, go to Device Manager). Does the card look okay? Has it been disabled or need a driver update? If we're still looking at issues then I would take a look at your router security. How many DHCP licences do you allowed to be assigned? Also do you have security in place (WEP/WPA, Mac Filtering, SSID Broadcast)? If you are light on security and only have a few assignable DHCP licences, you may have neighbors leeching your internet access.

To clarify: DHCP assigns a network IP address to each device on its network. Most Linkys routers have a default of 10, you may have reduced this yourself. If you have, you've limited the # of devices allowed on the network. So if you have 3 DHCP licenses available, and a couple neighbors are leeching, your Dell may not get assigned an ip.

If you still need further help, let me know.

use an newer explorer like g chrome beta or internet explorer 9.if it occurs again instal win vista as multiple os .vista is best for network connections .it will increase you browsing experience.

On the front edge of the laptop, 3rd button from the left is the radio on/off button.

You just need to remove the preferred networks on your vista, follow this.
Right click the wireless icon>network and sharing center>manage wireless network>remove all preferred networks.click OK.
Then connect again to your network that should solve it.

sounds like you have a virus/vista conflict..no easy way to balance that..without trial and error on settings for security and content

Hi,
In this case you have to get your router reset to default settings and then set it up once again and also setting upa new wireless network with a different channel because the issue you're facing is because of channel selection.
