I have a question and I wasn't sure where else to ask. I have a Clevo W150ER laptop with a Realtek wifi mini half card. In device manager in the properties of the Realtek wifi card there is an option under Power Management to "Let the computer turn off this device to conserve power". With that option enabled the wifi card will immediately connect to the wifi router after a sleep or hibernation but will occasionally randomly disconnect from the router. With that option disabled the wifi card will not connect to the router automatically, but when I connect it manually it will stay connected with no random disconnects. I have another laptop in the house (a Toshiba) and the exact same thing will happen on that computer as well. Any thoughts as to what could be causing that behavior? It seems I can't get the wifi card to both connect automatically AND not have any random disconnects.

Realtek Audio,Lan and Wifi are used by notebook makers to keep the price of the stock notebook low because competition is stiff.
Every Realtek WiFi card that I have tested in the last few years had disconnect issues unless I was in the same room and in line of sight with the router.
Are you using 2.4ghz or 5ghz?
Did you select the best channel?
Are you using Bluetooth devices on your notebook?
Is the router set to WPA2 AES?
If you are on 2.4ghz have you tried setting the wireless cards Advanced options for 2.4ghz channel width to 20only if you have that option?
Have you walked around your location with the laptop in hand while running inSSIDer FREE edition measuring signal strength to locate the best and worst locations?

inSSIDer will also help you to find least used channels.
Setting up and getting the best results on a home wireless network is not an exact science and takes a lot of experimenting;then all of a sudden a issue pops up
Do you have a quality router? -
Thank you for the reply. I will answer your questions but one thing I have discovered since I posted the original question is that I think the issue is with my router. I have two wifi routers, a Linksys AC1200 and a Zoom N150. The issue only happens on the Linksys router with both of my laptops (one with a Realtek card and the other with an Intel card). So I don't think the issue is the Realtek Wifi card. I have now asked this question on a Linksys support forum.
I am using 2.4ghz set to 20hz only
I have selected the best channel after trying several different ones, but I have not tried to identify the "best" channel with inSSIDer.
I do have a bluetooth mouse connected to one of my laptops, but not both.
The router is set to WPA2 AES
Again, thanks very much for the reply. -

I had not seen those articles, thanks for sharing. Apparently I DO have the 6400 board, not the 6300 board. I just bought this router a couple months ago (Dec. 2013) so apparently Linksys still hasn't gone back to the 6300 board. I am also running the latest firmware for the router. And thanks for the station-drivers link; I was not aware of that site. Are the downloaded drivers usually safe?

Yes, it's a reputable website.

Any idea why two networks show up? And if their coming from the same router, why would one lose signal while the other doesn't? Again, I don't have an AC network card, so I'm not seeing a 5ghz band so the second one can't be that.

I live in a high rise apartment building complex.
On the 2.4ghz band I show 3-co channel and 15 overlapping
Sometimes I can see as many as 75 SSIDs on 2.4ghz using inSSIDer
If someone chooses not to broadcast the SSID in their router setup then you won't see the SSID,only that there is one on the same channel
On the 5ghz band I show 0 co channel and 0 overlapping.
I always use the 5ghz band. -
And I can't figure out what it is.
