72 Mbps 802.11n wifi max speed on Inspire 4G?

---

Is anyone able to connect at higher than 72 Mbps? I Googled up an old forum post where they thought there might be a hardware limit? I just got a 802.11n router recently but I've yet to connect higher than 65 or 72.

Try messing with the settings on your router. I spent nearly an hour one day on my wireless N router and was able to get further reception. Never messed with the speed as too its not really an issue. 65mbs is WAY more than enough for a mobile phone. But if its that important to you I think it really won't matter how much faster you make it because the speed at which the sdcard can write data can't keep up with the data speeds of a high speed home data connection of about 10-20m anyway. Already I'm able to download at about 1.2mbs on large files which is the same speed as my computer when downloading large files.

Point is... no matter what you do to increase the wifi speeds on your router or your phone won't make a difference

Computers connect to the router at 150+ so I'm pretty sure it's setup correctly.

I know it will only effect in-network activities, but I was just wondering if there was a reason I couldn't get it to go past 72.

The photon supports up to 150. You could try going into your router settings and change the rate from auto to 150 turn your wifi off then on after your router sets and see if you get the 150 connection. It may also have to do with the rom. The photon also supports 5ghz wifi connections but on cm9 we are stuck using 2.4 because the setting to change the frequency is missing

Lol oops forgot I'm on the inspire thread. I'm not sure If the inspire supports 5ghz frequencies. Go to wifi, then hit menu and go to advance settings. There might be an option to switch between the two settings. Also on your router mess with the channels. I have had better luck on 9 than 11 with getting over 72. Also make sure the channel width is 40mhz only. The 20mhz can support up to 150mps but if your phone don't need it it will not force it. The radio on nearly all smart phones are automatic which means it will do what it thinks is best for your phone. Some roms I have seen on other devices have forced settings for wifi which gives much more control over how the phone reads from the router.

It looks like a limitation of Android device since I have 2 devices max out only 72Mbps.

There are a number of limitations that stop extra fast speeds on 802.11n.

1) Antennas
1 antenna = max 150 Mbps

2) Congestion
If you are in a busy area (like suburbia, 2.4 Ghz is used by more than just WiFi too) you will not get the 40 Mhz bandwidth for 150 Mbps, it will drop back to 20 Mhz bandwidth which means 72.2 Mbps maximum.

3) Guard Interval
If the distinct transmissions between between both units are not making it through, the Guard Interval will be doubled from 400 nanoseconds to 800 nanoseconds. Maximum now possible is 65 Mbps.

Most people will never see more than 72 Mbps on one antenna.

I max out around 35mbps of real throughput
