Hi all, The wifi issue I need to discuss is NOT talked about in this forum before (I have searched manually). This wifi issue of Nexus 7 2 was an incidental finding. I have this unit since 2 months now and at present I am on the latest build of MahdiRom (flo). Everything works fine and smooth except... the Wifi LAN upload speed is very low, around 170 KB/s (kilo BYTES). While the download speed is upto 1.5MB/s (Mega Byte). My old HTC HD2 (also on same Wifi local network) shows 1.0MB/s uploads and same download speeds. It seems that something is PREVENTING the wifi of Nexus 7 2 from reaching its max. upload speed. This issue persists even on STOCK ROM (KK 4.4.2 KOT49H). I tried to do the speed test of wifi local network through a wifi adhoc connection but didn't know how to do that. Instead, I used an app called Fast File Transfer" (https://play.google.com/store/apps/d...transfer).This app uses Wi-Fi Tethering for establishing a connection between the devices but does not need the Internet. And to my surprise it showed upto 2.1 MB/s upload speed of Nexus 7 2, meaning that the wifi adpater is working fine!!!

My setup:
1. Wimax broadband modem (DHCP is ON, IP: 192.168.15.1)
2. Linksys WRT54G (DHCP OFF, (acitng as a wireless access point) Set to Wireless G only mode, Security set to WPA-2, IP: 192.168.15.10)
3. HTC HD2 (Android Gingerbread 2.3.7 custom rom by JauguarAlani, IP: 192.168.15.15)
4. Nexus 7 2 (2013) (Mahdirom latest build KK 4.4.2 ( build number KVT49L)

I hope you get the picture.. I would be much grateful if anyone would kindly direct me in the right direction. Thanks

N.B: Also tried FTP method, but still the same speed.

I presume the IP address in 1&2 (.1 & .2) is a typo. What is the speed of your internet connection as claimed by your ISP or tested?

Thanks for responding. NO, there is no typo! The Wimax Broadband Modem has an IP: 192.168.15.1. It is the Gateway and its DHCP is ON. The Linksys WRT54G has an IP: 192.168.15.10 (static), and its DHCP is OFF. All other devies also have static IPs. The speed of my Internet Connection is 1.0 (one megabit/s) and I am getting slightly more than what I should be getting. This issue strictly has to do something with my Local Wireless Network. Thanks anyway.

My router was set for "G-Only" devices so I tried the option "Mixed" that is, B and G both. And it worked!! Although it doesn't make any sense, since my HTC HD2 (a four year old phone, running Android GB 2.3.7 was already performeing very good with the G-Only setting, but anyway, my problem is solved!

makes sense to me, since the router would be doing a lot of extra work to make sure it only used the newer protocol, and somehow it interfered with the nexus...But glad your solved!
