Laptop has no Internet Access but the router is working fine

[kkjoo]

So since last week my laptop(Acer Aspire 4752G) would suddenly lost the access to internet with no apparent cause.

I can connect just fine but every once in a while it would suddenly display "No Internet Access". But when I checked the router it's running fine and the other devices connected to that wireless network has no problem at all. I can fix this problem by resetting the router but recently it's happening with greater frequency and it's very annoying to reset the router every time this happened. Not to mention my family members would be mad if I keep resetting the router every few hours.

So anyone can help fix my problem?

Ttry releasing and renewing DHCP by following the link http://customer.comcast.com/help-and-support/internet/releasing-and-renewing-ip-address/. If you are on wireless connection, perform "forget the network" along with the renewing DHCP. Check the link for the same http://kb.linksys.com/Linksys/GetArticle.aspx?docid=85537a14b0214be48217c733bba9ac65_Removing_Wireless_Network_Profiles_.xml&pid=80&converted=0.

Thanks but I tried that and the problem still persist.

Could be two different issues:

1) Make sure you wifi card drivers are updated.

2) Make sure you dont have your wifi card set to "save power while on battery by turning off."

I have seen the second option cause problems multiple times but it only affects users while running off battery power without the charger being plugged up. To check this, go into your power options and check your plan settings to make sure it doesnt turn off the wifi card when running off of battery power.

1) I just updated it earlier because I thought that might be the problem but since it keeps happening nonetheless I think that's not the problem.

2) I'll try this but I also don't think that's the problem since my laptop is plugged on all the time.


Or could it be that my wireless card itself is dying and causing this problem?
