[Q] Wireless n limited to 65Mbps?

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.
http://www.broadcom.com/products/Bluetooth/Bluetooth-RF-Silicon-and-Software-Solutions/BCM4329

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.

Slow Wifi on 2.4GHz and 5GHz

Hi guys,
Never really noticed before, but running tests on both Wifi bands on both my nexus 5 and nexus 7 reveals the nexus 5 to be almost a third slower than the nexus 7!
Consistent d/l speed on nexus 5: 10-16mbps
Consistent d/l speed on nexus 7: 45-55mbps
I have fibre optic broadband at around 65mbps.
I even get higher on 4G (UK) reaching around 30mbps.
I've tried both bands at home and both yield the same, slower speeds on my nexus 5.
Anyone have any ideas as to why this might be?
Thanks,
Td

I achieved higher speeds when I set the control channels in my router's settings to the lowest channels possible.

Try upgrading the firmware in your wireless access point.

2.4 GHz Wifi Performance

I've noticed very poor performance when using 2.4 GHz wifi on my G3 when compared to other devices. I can have my Nexus 4 and G3 sitting right next to each other on 2.4 GHz WiFi and the G3 is consistently slower when doing a speedtest like speedtest.net or iperf. Usually the G3 gets around half the speed of the Nexus 4 or worse. On occasions i've seen the G3 start getting below 1 Mbps or nothing at all and the the only way to fix it is by putting the phone into airplane mode and taking it back off.
When the G3 is connected to 5 GHz it is pretty much on par with the Nexus 4 when doing speedtests. I've also not seen any of the strange slowdown issues that require a reboot or airplane mode toggle on/off when connected at 5GHz.
Makes me wonder if i got a defective device or if anyone else is experiencing the same issues. I'm still within my 14 day return window but i'd hate to go through the process of swapping out the device and tweaking everything back to my preferences if this is an issue that will likely be fixed with a software update.
Has anyone else noticed issues with their device when connected to 2.4 GHz wifi?

Where did you find the settings for Wi-Fi freq?

You select the frequency when joining the network. If you have a dual band wireless router and have both frequencies broadcasting, the option to chose which band will appear when you are searching for wireless networks.

I get 50.28Mbps down and 20.11 Mbps up when testing with the Speedtest.net Android app on a 2.4GHz frequency router

Just curious who is your ISP ? 20 mbps up is awesome and I wish I could get there lol. I run 45 ish mbps down and 4.5 megabits per second up on suddenlink cable ISP on 2.4GHz

Verizon was nice enough to recently upgrade all FiOS customers with symmetrical bandwidth. Your upload now matches your download and in my case exceeds my download for no additional charge.
Not quite as fast as Google Fiber but Verizon's highest package is now 500 down/500 up.

It's Comcast. The 'Extreme 105' plan, I believe

Is your bluetooth turned on? If so turn it off and re run Speedtest.net. I have had a few phones that do not play well with bluetooth

Nvidia Shield Tablet WiFi signal

My WiFi signal seems really slow and weak I have a pretty fast WiFi connection on all my other devices is there anything I van do?

What is the signal strength?
Ideally you would want all of your bars, but 3 should be good enough.
How many devices are using the internet at the same time?
What signal is the router broadcasting?
In have had no problems, except in my bathroom, were the signal goes down to one bar and "slows" down the connection.

I noticed that when your hand is over the left hand corner it will make the signal drop a bar or two and when you take it off it goes back up..weird

After upgrading to Android 5.01 via OTA, my upload speed for 802.11a 5Ghz band improved quite a bit giving me 50 meg down, but when switching to use the 2.5 GHz band on my router, speed drops to ~3.5 meg down. I checked speed on my Nexus 4 using the 2.5 GHz band and got around 35 meg down. Something is not quite right with the Shield WiFi when it uses a WiFi network using 2.5 GHz band.

That's why Nvidia says to specifically use the 5Ghz channel, not the 2.4Ghz.

I haven't received anything specifically from Nvidia stating not to use 2.5 GHz channel. Not everyone has a dual channel wireless router, so to upgrade just for the shield maybe not in the cards for some. There has to be a better answer than 'use 5 GHz only'. Most public access points aren't 5 Ghz channel.

Does the Huawei P20 supports 2X2 WiFi AC?

Hi, I want to know if WiFi AC (5 GHz) is working on the Huawei P20 before buying it because I had an awful experience with it on the Mi A1. Also what link speed are you getting.
Thanks in advance.

Hey,
It's working fine on my P20. Just the one thing I noticed is that the phone didn't see the network on first boot and it needs to refresh networks to see it sometimes. (I might try to switch channels and see if it gets better) But overall I'm running on 5GHz all the time and had no issues, it's blazing fast.
Screenshot with Ookla speed test - multiple similar scores - I have a '100' Mbps optic fiber.

Sorry by a mistake I quoted myself on XDA labs instead of editing the post and idk how to delete this...
ALSO it's not fiber optic, sorry. but it is 100 Mbps connection. *

Yes 2x2 WiFI AC i get 867 / 867 Mbit/s connection
