I have a decent internet speed on my Ethernet hooked computers in home with 85Mbps.
I use a wrt54(8 years old) as my wireless access point and only get about 20 Mbps tops on iPhone and iPad. Any recommendations for a router or access point(disable DHCP on router) that will improve the speed to what I have on wire with some ability to penetrate 100 year old lathe walls okay?
