My router can support max 450 mbps in 802.11n. However, Nexus 5 only connect as 150 mbps. Is that because it only has one antenna in its Wi-Fi chip?
Thanks

Yep, N is basically limited to 150mbps per antenna.
As mentioned it's a 1x1 radio so the max it will do is 150Mbps link rate. Not that you'll ever get those speeds but yeah, that's as fast as it can connect.

I have noticed on my Nexus S that when I do a speedtest over the wireless it caps out at like 5Mbps and when I watch my router control panel for the thoughput speed it peaks at 8.5Mbps yet if I do it from my laptop the speedtest on the same server reaches 32Mbps and the router is putting out 37Mbps over the wireless.
My router is in G-only mode and forcing 54Mbps since all my devices are G/N capable. Is anyone else noticing slowness with their wireless on their Nexus S?

Hi all,
I am getting approximately 215 KB/s transferring a file (over scp/ssh using AndFTP) from my PC to my Xoom over my wireless home network... I have a linksys WRT610N wireless G/N router... PC connected to it with ethernet cable running @ gigabit.
Anybody know why these speeds are so slow? I should be getting a better rate than that...
Thank you!
Same here, same router and maximum I get is 3mbps.
Just ordered my TF... was wondering if it would be able to pick up 5ghz WiFi, or is it only capable of 2.4

See technical specs 2.4 only.

It's 2.4GHz only.

Mine wouldn't connect to my 5 GHz band router. Should have checked that before I bought it!
I'm now uploading my nandroid backups (about 3GB each) to Google Drive and it's painfully slow at my current speeds. I currently have a wireless G capable router/modem (Actiontec FIOS router) so it's only capable of uploading at a max of 18mbps (~2.2MB/sec). Turns out it's a few generations behind and now there's N and AC speeds available. Looking at the Nexus 5 specs, it supports N and AC. What kind of speeds are people getting?
Hi i only own a LG G2 but should be the same with WLAN speeds.
On N i get 150mbits
And on AC i get 433mbits
think these are the realistic maximums even when the router spec sheet says up 1300mbits
My laptop connects with 300Mpbs. But my Xperia connects to the same access point only with 72Mbps.
Mine too.
My original Z did that as well, but my wife's G2, and my dads knock off Chinese phone connect at 150...

The Snapdragon Chipset only has one antenna.
Most Phones
N Mode
1 antenna in 20Mhz mode = 72 Mbps Link
1 antenna in 40Mhz mode = 144 Mbps Link (Aka 150)
AC Mode
1 antenna = 433 Mbps Link (I get this as I have an AC router: Netgear R8000)(Z3 gets around 240 Mbps peak transfer speed)
Most Laptops
N Mode
2 antenna in 20Mhz mode = 144 Mbps Link (aka 150)
2 antenna in 40Mhz mode = 288 Mbps Link (aka 300)
AC Mode
2 antenna = 866 Mbps Link (My laptop with Intel 7260AC adapter gets this link)(Gets around 320-400 Mbps peak transfer speed)
Reason for single antenna is to save power. The Snapdragon 810 Chipset will have a 2x2 antenna (aka 2 antenna).
40 Mhz for 2.4Ghz Band is generally not preferred in residential areas with lots of WiFi users/congestion as it uses more channels causing interference and may actually lower your effective range.
This is why older Apple products and Intel adapters at one point did not allow 40Mhz mode for 2.4 Ghz. Modern routers automatically drop to 20Mhz if they are conflicting with your neighbors and many don't let you force 40Mhz mode only supporting auto switching based on interference or the other option being 20Mhz mode, this applies to all Intel adapters as well.
Also these are link speeds not the actual transfer speeds, in N mode my laptop drops from 300 link speed to 240 or 144 due to many neighbors having WiFi. That's why I use 5Ghz N or AC as very few people have this.
Remember actual throughput will always be less than the link speed due to overheads, generally around 60-70% of the link speed with good range/signal.
The best transfer speed on the Z3 at 433 Link speed for me is around 240 MBps.
I still can't understand
1. Why my laptop use 2 antenna in 40Mhz mode = 288 Mbps Link (aka 300) and in the same time my Z3 use 1 antenna in 20Mhz mode = 72 Mbps Link with the same wi-fi access point.
2. And why my Z3 don't use 1 antenna in 40Mhz mode = 144 Mbps Link (Aka 150).
Yeah I get that too, Sony probably did that to avoid interference. Even my dads M8, sisters GS4, mom's iPhone 6 does that.
20Mhz means Less interference so longer range and battery life due to less packet resends. I doubt it would impact you much if at all. If you really want more bandwidth switch to 5Ghz mode though range will be less unless your on 5Ghz AC.
In N mode even my laptop drops link rate from 300 to around 270-144 most of the time because neighbors also use WiFi obviously.
