I am looking to replace the existing Broadcom 802.11 a/g/n wireless adapter that original came with this computer. I have installed a new network 801.11ac router and want to install a 802.11ac \ a/g/n wirelss adapter. This is necessary because the existing wireless adapter makes me back down the throughput 2.4gig to 54mb on the router. If I try anything faster I connect to the router but, with NO internet connection. To clearify, I have other 5 computer on this network and this is the only computer that is having this problem; the reason for wanting to replace the internal wireless adapter. Thanks in advance for any help or suggestion that will be compatable with this Acer Aspire E1-531-4694 Notebook.
