RE: Dell Inspiron 1545 network controller driver needed!!!
I have an Dell Latitude E5400 with Broadcom BCM94312HMG card. It keep disconnect and connect from internet. It is not signal because the signal strength is strong. There is no connection or signal problem if I use and USB Cisco wifi plug. It seems to be the driver problem. I change the Broadcom BCM94312HMG card with a new card and I have the same problem. It is not the problem with card. I avoid the problem by using the USB Cisco wifi plug. It works all the time now. It is a shame for Dell for lack of support. I will not buy Dell again.
