I'm getting 5ghz hotspot speed as well as 2.4ghz speed only 72.2 mbps.In previous roms transfer through 5ghz used to be very fast. Can someone confirm if it's issue with the rom?
No, in my case it's 433 Mbps.
This is hardware problem. You have to buy this board:
You can buy New SIM Card Micro-HD Flex Cable for LG E900 Optimus 7 from ebay.com, sefelectronics.com or mobile-cherry.com.
I recommend to buy it from mobile-cherry.com. It 100% works! :)...
