Whats The Best most compatable Wireless AC Wifi for W520

[upgrades]

I have 6300 wifi installed at moment but wifi has much improved since. Someone have any personal hands on experience on improving the internal wifi for this lenovo model? I dont want to damage the laptop doing this upgrade. Thanks for your help

Your system won't accept a newer card without a modded BIOS being flashed first. Whether that's a risk that you're willing to take is entirely up to you.

My opinion is that AC wireless range is barely out of diapers and that waiting from a few more cards as well as router chipsets - mainly from Qualcomm/Atheros - would be a smart thing to do.

ill take your advice and wait for someting more compatible from intel. The 6300 i have inside should be more than enuff for now. Its 300-400mbs right?

I upgraded my T520 to the Ultimate 6300AGN and it performs very well. Better than on the old card. It connects immediately upon boot or resume from hibernation or sleep, whereas the other card would not do that and would take up to a minute to connect in most cases.

A BIOS reflash was neccessary but went smoothly.

I believe the 6300 is the best you can get, so keep your current card. It's what I'm using, and no complaints at all.

With a modded BIOS (whitelist removed) the Atheros AR9380/AR5BXB112 is even better and faster (450mbps).
