do imbedded wifi cards fail very often ?
my wife laptop is like 12 feet away from the AP and gets 1 bar,
when I go close it's like 3 bars, no interference between, line of sight.
I checked the network adapter in the network settings, transmit is on high,
maybe something in BIOS?
The antenna cable might not be seated fully. Has it always been like this? Has it been knocked at all. Has any updates installed new drivers?
You could run a Linux bootable ISO and check if the same isuse is there, if so then probably hardware-related.
Also, I bought a 802.11n (2.4GHz) mini usb dongle that is barely noticeable when plugged in, for <$5 from ebay. Could be an idea...
^ New drivers, always check those drivers.
I need to do that, I resolved it bu turning on a new 5GHZ 102.11ac radio on the AP and setup the laptop to use it. seemed to work much better,
Could be interference from nearby wifi on the same channel. I've noticed here that people are trying to improve their crappy wifi by enabling 40mhz-wide 802.11n 2.4ghz. Since with a 20mhz wide channel there are only 3 channels, if you have one silly person in the area with 40mhz wide then this leaves only 1 free channel but most of the time they're also using a channel like "9" which makes the problem worse.

In the 2.4 GHZ, the laptop is like 10 feet (3m) away from the AP, and only gets 0 or 1 bar. It does not see any of the neighbors AP's. (Sidebar, wife didn't have the wifi auto connect feature enabled so at 0 bar, disconnect and never reconnect until done manually. I fixed that.). Daughter and her laptop 20 ft (6m) away, gets 2-3 bars all day on 2.4Ghz, has no issues like the wife Toshiba laptop. Only when I place the wife laptop right next to the AP, does it get 3 bars, not even 4.

Yes you're completely right. I must not have had my coffee this morning :)
