Has anyone been able to exceed wireless n speed of 65 Mbps on their Captivate?
My computer reaches speeds of 135 Mbps but with my captivate right next to the router, I don't see anything above 65 Mbps.
Edit: I'm just using the speed it tells you when you click settings->wireless and network->wifi then I just tap the SSID and look under speed.
Also I set my router to only use the 40mhz band. I just want to know if even 1 person has seen anything over 65 Mbps, so that I know whether it the phone or the router.

Dumb ? Is your computer using dual-band?
Edit: also, the Cap might be operating in 20mhz bands intead of 20/40... (nasty technical details)
How did you test this? ALso usiong no encryption helps....
Also I didn't know captivate have N band 2.4?
EDIT:
a/b/g/n dual spectrum capable.
My guess? driver.

I am thinking the driver has some issues in general.
Random loss of connectivity and need to disable enable wireless to get connectivity back.
Slow 802.1x connection speeds (11mbps max from what I can tell)
N only connects on 2.4Ghz band and not 5Ghz.
So, yeah, my guess is driver is gimped a bit.
I have no issues with Wifi. BTW, iPhone 4 also uses only 2.4 Ghz band for "n". As I understand, 5 Ghz would require additional antenna.
Also get max of 65 Mbps
Was disappointed when I saw my Captivate which is advertised as having wireless N just barely connects above wireless G speeds. Both laptops easily gets 130Mbps from the same router.
N speeds on a 20MHz band will be 65Mbs. Your laptop and desktop most likely have a 40Mhz bandwidth antennae which allow you to get up to 135Mbs. The Captivate has an antennae that will only work on the 20MHz band which is why you only see a max of 65Mbs. I remember reading about why this is and I can't find the documentation any more.
Anyway, while this does seem "barely higher than G speeds" it's actually a big difference. The wireless N standard added the function of Multiple Input and Multiple Output (MIMO) antenna's which increases the signal throughput. The wireless G standard does not have MIMO function in it. The increased speeds and the addition of MIMO antenna's makes the Captivate's N wireless much faster than a G wireless even though the Mbs are close together.

And, just to answer it in case someone is thinking it .....
Having your wireless on 5GHz vs 2.4GHz will not increase your Captivate speeds above 65Mbs. This refers to the frequency of the signal which is different from the signal bandwidth. The 5GHz range was added with wireless N to avoid interference from other 2.4 MHz devices such as wireless keyboards, wireless mice, home telephones (people still have these?), wireless gaming controllers, etc.
While 5GHz is nice, as it is a separate frequency to help avoid interference, it actually has a shorter broadcast distance since it's a higher frequency. It will also have a harder time broadcasting through walls and other solid objects since it's a higher frequency.

Good information
Thanks for the information. Am always much happier once I have been given an explanation to a question.
With some of the leaked GB 2.3.x builds, I have gotten 72 mbps when my router is set to N only mode, locked to 40 Mhz width, WMM enabled, WPA2 personal "AES only" encryption, with all options for "neighborly" radio turned off, and standing within 6ft of the router.
65 mbps was the highest I ever got on CM7 or Froyo and even the GB builds don't hold at 72 mbps for long.
My Captivate does connect to 2.4 Ghz with 40 Mhz width. 5 Ghz won't work though.
Ya my internet doesn't go over 2 mbs. 65 would be a dream.

Humm, I've never gotten anything higher than 65Mbps even on 5Ghz. However I've never tried it on 40Mhz width as I thought it wouldn't work. I'll have to test this out and see.

I have a problem with every ROM except TPC's in that I get crappy HSDPA and HSUPA speeds. In TPC's V2 I get 3 mbps down and 1.3 up with 85 dBm reception. In LeeDroid, AR, and CM7 with the same 85 dBm (doesn't matter which radio or how the build.prop is configed) I get 1 mbps down and .2 up. I do not understand and it is driving me up the wall. If I can get cellular data working properly on CM7 stable I will be as happy as a crackhead that got crushed by a giant crack rock.
my data is never consistent I blame that on att. There was three days straight I got nothing more then 56k down and 5k up. Then there are days I get anywhere from 5mb down to 1 mb down. I don't think it has anything to do with the rom or radio as much as it does with att's crappy network.
I have a thunderbolt and although when I run speedtests on the phone I get 10+ almost always. When i tether using wireless tether or barnacle I am lucky if I get 1.5. Is this the same issue on the charge? Are you able to run a speedtest on your laptop connected to wifi and get fast speeds?
Thanks
I get around 10 mb/s on speedtests app but I ALWAYS have a 1 bar at my house, it's probably just my low connection but who knows, 10mb/s is still insanely fast
I get about 15 down doing a speed test tethering from my laptop. Average download speeds on torrents, I can hit over 2 MB down. Cant complain.
I use a tplink wr 841 hp router, connection speed is 5/6 Mbps. in the full coverage area of the router, if I download on PC, i easily get 5/6 Mbps, but in mobile speed is wildly fluctuating, like 0-2-4-5-3-1-5 Mbps.
I use a Galaxy S7 , My brother uses HTC desire 820 (snapdragon 615). I found speed fluctuation on both of the devices,
There is not so much wifi's in my place, I get 3-4 other wifi while searching, then How can i improve my speed ?
My house has 50/20 Mbps internet. I'm using dual band WiFi, 5GHz on one router and 2.4GHz on another access point, both sit at the same location.
Previously I've been using 2.4GHz when I'm on 2nd floor with no problem gets about 30 Mbps when doing speed test, which is acceptable by me.
I'm not sure when but maybe within this few months, speed when I'm using on 2nd floor drops to 5 Mbps or sometimes even low as 0.3 Mbps. My iphone 4S still gets 20-30 Mbps.
Signal strength is the same as before about -70 to -80 dBm
It has no problem when I'm in line of sight from the access point.
Has anyone been experiencing this? And any solution
Thank you
PS. I still haven't reset the whole phone yet, but I have tried resetting network settings
