Help! Wireless Problem Inspirion e1405

Fresh out of the box w/:
T7200 2.0 Ghz
2 GB Ram
160 GB Hard Drive
WiFi Link 4965AGN
Vista Home Premium

The wifi card has no problem detecting wireless routers around the laptop. The problem is that it won't connect to the internet and sometimes not even to the router. Usually it will only let us connect to the router, but keep it "Local Only".

I pop open the network/sharing center and there's a green line between my computer and the router, but a fat red "X" between the router and the all important internet symbol.

Once or twice it connected, but only for a minute or two before collapsing into dismay...These are not run of the mill 1 or 2 bar spots...This is starbucks where I'm 5 feet away from the router...it says it has an excellent connection...

Any suggestions on what this might be?

Vista tried it's best to "repair" the problem, but didn't do anything to help...



On a side note for those with Inspiron E1405's w/Vista...

When I open my laptop from sleeping/hiberation the screen flickers a few times. I was wondering if that was normal? b/c I've never seen a laptop do that before...I got the true bright + glossy + ultrasharp...Anyone else run into that?

Any help is appreciated!

 

I think it may have been McCafee Security Center's auto-firewall that was preventing us from going onto the internet...

I will update you tmr when I goto a hotspot...

Any input is still appreciated tho!

 

Second update for anyone that cares...

McCafee Security Center's auto-firewall was the problem. I don't have a wireless problem anymore just a mental one.

The screen flicker when resuming windows vista after sleep still bothers me, but I want to know if anyone else is experiencing that problem. Vista laptops please respond...

Sometimes it changes the resolution to a lower resolution 1024 by 728 is what it likes to do...

 

CAN U JUST CHK THE SECURITY SETING OF THE ROUTER ON THE ROUTER WEBPAGE WILL LET U KNOW THE STEPS../

CONNECT THE ROUTER TO THE LAPTOP DIRECTLY (HARDWIRED)../

THEN CLICK ON

START-->CMD-->IPCONFIG-->CHK THE DEFAULT IP ADDRESS (IT WUD BE LIKE 192.168.X.X) --> TYPE THE IPADDRESS IN THE "Internet Explorer With http://192.168.x.x--> THE ROUTER WEBPAGE WILL OPEN DISABLE THE WEP or the WPA KEY IF THEY ARE ENABLED..

U CAN TRY THE METHOD MENTIONED ABOVE

 

for the screen flicker problems, d/l the Dell video driver for your system off dell.com
