    Upgrading intel wireless card


    I have a refurbished Lenovo Y40 and I am happy with everything except the wireless card. It is an intel ac-3160 card but right out of the box it had many problems. Internet signal drops off significantly when I am more than 5 feet away from the router.

    I know this is normal but my computer's internet speeds die down significantly faster than other computers with the same wireless card. For example, at around 15-20 feet away, this computer will have 0.5-1 mb speeds while a different lenovo (same card) will have around 8-9 mb.

    I want to try buying a new wireless card such as the intel-7260 or a new intel-3160. Does anyone know how to make sure my computer is compatible with the 7260? I have read an article about checking the "BIOS whitelist" to see if it's compatible (Page Not Found (404) - CNET

    Anyone have suggestions or tips?

    What router do you have? Upgrading the card or going with a USB adapter is not necessarily going to change something or improve signal if you are using a public hot spot at say a College or University dorm.

    The antenna is usually on the upper left side of the lid. My son swaps between his Intel Wireless-ac dual-band 7260 and a Netgear A6200 USB adapter, depending on where he is at on his school campus.

    Thanks for responding!

    I have only tested my computer on two connections, both in homes. For example, one home is using the motorola SBG6580. It is a 3 bedroom one story house with the three rooms being adjacent to each other. The router is in the farthest room and I cannot keep a stable internet connection from my room. I had to resort to buying a 50 ft ethernet cable and use that whenever I am in that house. What is the antenna you are referring to? Is that the slot where the wireless cards go?

    download the service or owners manual for your laptop..

    find the wireless card access and verify the antenna cable is attached... Although it could just be the card is failing.

    I rarely own laptops with Intel Wireless on it. Being a Lenovo, just buy the Lenovo version of Intel 7260 so you don't run into the unauthorized wireless card detected. My guess you get a 50% chance of getting improvement from 3160 since they both use the same drivers, PCB and architecture. I never had problems with WiFi though.

    Since the Access Point is far away from where you use the computer, your setup can be solved by using a Power Wifi adapter, vs. running a 50' Ethernet across the house, unless you placed it inside the wall.

    I keep a set of Ethernet over Power adapters, when I have to go out to my garage and work out there, due to my wifi signal does not reach inside the garage.
