Intel Pro/wirless 3945 problem
Hi all:
I just got my new laptop Inspiron E1505 with the internal Intel Pro/wireless 3945 mini card. I have problem with connect to the internet.
If i leave my router open and unsecure then I'll be able to connect to the internet fine but the download speed is very slow 16-25 KB/sec compare to 120-150 KB/sec on my desktop (Laptop is next to the router).
If i set my router with secure password using WEP or WPA. I cannot connect to my router and if it can connect ... it only stay connect for 3-4 second and then disconnect. Sometime, It connect and if i load up a yahoo page and click on a link .... It will disconnect right away. I know that i setup WEP or WPA correctly because i tried it with a different wireless adapter and it worked fine. I've also tried D-link, Linksys, Netgear, and US Robotic router ... but none of this works on my Intel Pro/wireless 3945 mini card with WEP or WPA opion .... I don't want to leave my router open and unsecure.
I have tried windows and Intel utility to manage my wireless .... but it still does not work .... help me please. thank you very much
I received my E1505 last week, and I am noticiting the same thing with the Dell minicard. I've got the Windows Firewall turned off and the system is fully patched, sitting behind a netgear wireless router. My other laptop is hardwired to the router and its speed is normal. My wife's laptop is also wireless, and its speed is normal. Any help would be greatly appreciated.
- To change just one thing, independent of the router itself have you tried simply turning off Windows firewall and any internet security software on the new laptop? Also, make sure you have run ALL Windows updates (there will be two or three dozen on a brand new system).
- You might have a bad card. Check out the thread below
- I called the dell tech support and had a talk with them for more than an hour ..... they decided to send me the new card ...... i got it today ...... It takes less than 10 minutes to take the old card out and put the new one in .... ..... It works now ....fast down load speed .... and connect with WPA2 security. Thank you to all.
- I don't have the tech support name, the tech support is a lady...... like i said ... i had a talk, trouble shoot, and wait for more than an hour ...... They asked me to do alot of things but the card is not connected .... and finally they decided it is a defective card ... ... infact, it is a defective card ..... i got the new one... it's working great now...
- You may want to check out the router. I received my 1505 3 days ago. Spent several hours trying to figure out why my intel 3945 was working 1/4 the speed of my older laptop & pc that connect in through a 3yr old Linksys router. Changed all power settings, etc. and nothing worked. Finally went out and purchased new Linksys router & installed tonight. Speed is outstanding.Called dell support last night and they were helpful (if you can make it through the numerous restarts they put you through). They recommended the new router even though I didn't think that was the issue.Everything else on the 1505 working great.

Did you also go to "Configure" and CLEAR that checkbox "allow power off" so that the adapter's power is always full ?
