Hello guys. I just bought that router few days ago. After configuring i found out that 5 ghz is not showing in my phones. I had a firmware upgrade but did not worked. Then i contact my mobiles customer care and they told me they supports 5 ghz. Then i go to the shop from where i bought it and they checked the router and told me it's connecting with laptops and it is fine. Then after getting back home i connect my mobiles via wi-fi tethering and installed a app named wi-fi analyzer and it showed me they are using 157 or 161 5 ghz channel. Now in router i only have 4 channels (36, 40, 44, 48). So i think that is the problem. Is there any solution for that? I posted a thread in 'Tp-Link' forum and they didn't approved it yet even after more than 30 hours and also sent a mail via support option but no response yet.
