no options available in Latitude E7240 wifi adapter (1506)
I am trying to increase wireless network speed. The highest I have gotten (per speedtest) is 48 Mbps. I noticed that the adapter's config only has the option 802.11b preamble. There is no option for g/n. The adapter is a Dell 1506 802.11 b/g/n 2.4GHz. According to Dell, the driver is up to date (v.10.0.0.341). I think this is a driver problem, but so far I have not found anything definitive on the net or this Dell support site. I need some advice on how to fix this problem. Also, does this adapter only support 2.4GHz and not 5GHz. Thanks!
