[Q] Wi-fi Speeds

Hi
Wonder if anyone experienced the same problems as me.
The Wi-fi speeds I am getting is around 30 mb on my nook, although this is a reasonable speed I noticed that it goes down sometimes quite a bit. I belive the nook can only connect to the 2.4g wifi and not the 5g.
In comparison my windows laptop (2.g) gets 50mb
My Iphone gets 55mb and my other Windows tablet gets around 45mb
I now the Nook is quite old now so is it just not able to pick up high fiber-optic speeds or is there a fault somewhere?
Thanks

Yes, the Nook only supports 2.4 GHz 802.11n, with a maximum MCS index of 7.
What does that mean? Wikipedia has a handy table here.
It might look confusing at first, but here is how it works. The maximum data rate depends on three factors (apart from the modulation type):
1. the number of spatial streams (basically antennas, 1-4)
2. whether or not 40 MHz wide channels are supported
3. whether or not short guard intervals (GI) are supported
The WiFi chip in the Nook has only one antenna and supports neither 40 MHz channels nor short GI (at least it's set up that way in our firmwares). Therefore, the maximum achievable data rate is 65 MBit/s.
It can also be lower, if the signal is weak. You can check the current number in Android's WiFi settings, by touching the name of the WiFi you're currently connected to.
However, that's the link speed, the theoretical maximum that also includes WiFi protocol overhead. In practice, you can consider yourself lucky if you achieve about half of that for payload / user data.
So, if your tablet is connected at 65 MBit/s, you can expect a usable data rate of about 32 MBit/s at best (3.8 MiB/s). The final data rate can also be throttled even further by other system components, like bus and CPU speed, etc.
My phone for example also has MCS index 7, but supports 40 MHz, and therefore has faster WiFi with link speeds up to 135 MBit/s. And my notebook has MCS index 15, two antennas, with both 40 MHz and short guard interval, therefore achieving 300 MBit/s (provided of course your WiFi router / access point supports that as well).
Long story short, the relatively slow speed you're getting on the Nook is probably normal and by design.

Thanks for the detailed post.
I am guessing that 30 mb is quite good then in comparison

Your speed is about all its going to get but in comparison to it being bad? Its rather bad...

No Data at 5ghz

Hey guys, I recently picked up a Nexus 6 and when trying to set it up I noticed my Wifi download speeds were terribly slow even though im rocking a 200mbp/s download speed. I'd try and download speed test but my signal was too slow so it would time out. So I sideloaded speedtest and got a download of .02 mbps on 5ghz and .5 on the 2.4ghz band. Can anyone help?

What channel is your router on?

2.4Ghz is on channel 1 and 5ghz is on 44

My 2.4 is on auto and 5g is on 157. Works great for me.

has anyone tried the wifi speed increase hack/mod?

I was browsing and saw a mod for some phones to increase WiFi speed.
So i had a go and it significantly increased the speed.
-----------------
The changes are in the following file:
WCNSS_qcom_cfg.ini
Changing the following line:
gChannelBondingMode24GHz=0
to
gChannelBondingMode24GHz=1
-----------------
Any one can explain what it actually did?
Seems like a simple change for a big difference, but not sure if i had inadvertently stuffed something else up.

It forces the phone to use bigger channel widths on 2,4GHz , but it doesn't really matter these days.
Just get a 5Ghz network if you want speed, for example 2 internal speedtests on the mi5 on a 2 and 5 ghz 802.11ac network:
2,4Ghz N 40Mhz : 67mbit/s
5Ghz AC 80Mhz: 430mbit/s (my laptop gets 700mbit easily over wifi , too bad the Mi5 doesn't have enough antennas for that)

What router do you have?
On my old Linksys EA on 5GHz band Mi5 doesn't connect above 150Mbit/s. Router is supposed to be N300+N300 and has 2+2 internal antennas.

Android 7 - 5Ghz WiFi slow

Jun-3 2017 got OTA update a few weeks ago. T813 doesn't have problem connecting to 5Ghz wifi but on 5Ghz the connection is slow. Appears to be capped at about 10MB. Whenever I run speedtest while connected to my 5Ghz network I get 10MB uploads. Disconnect from 5Ghz, rerun speedtest and I get 80MB uploads. Go back to 5Ghz rerun speedtest, back to 10MB. Can reproduce this every time.
I guess I am stuck not using 5Ghz.

change channel to 40 (on router/AP).. and test,.

Found this in a different thread. Changed to channel 40 and speedtest shows upload speeds of 80MB. Netgear recommends using channels above 149 but I will stick to 40. Anyone know why using the lower band 5Ghz channels gives higher speeds than the higher band channels?

do you happen to be using a euro model in north america? what is your CSC and which country are you using the device?

On router (if possible) change channel width to 20 any frequency should fix wifi. Atleast for me this worked

After changing the routers channel bandwith, this thing goes from 10 mbps to 80mbps. They need to fix this. All my other devices max out at 235mbps on 5ghz. This tab is too advanced to be doing this.

Had the exact same issue on my new T713 and the channel width change from Auto to 20 worked for me on Asus router. Left the Control Channel on Auto. Thanks!

I had this same issue too. I had to turn off Power Save Support then I didn't have anymore 5 GHz slowdowns

Mine had the slowdown with Power Save off - the channel bandwidth was what fixed mine.

hey guys, my download speed is very slow on 5ghz wifi, but few time ago was working well, I dont know what happened. My macbook reach 120MB download and 10MB upload, but my galaxy s8 shows 10MB dowload speed. I tried change my channel width on router, but didn't work.

I'm finding 5GHz to be a real mixed bag across all of my devices - Tab S2 T713, 2 iPad Air 2's, Dell XPS 13 9350 laptop, a Lenovo desktop, 2 Dell desktops, and a Galaxy S7 Edge phone. Performance seems to be inconsistent and I see complete dropouts where the band isn't even visible on some devices. This is irrespective of distance from the router, an Asus RT-AC66U_B1, number of connected devices, etc. When it's good, I see 120MB/sec but other times it will drop off by 50% or more or will disconnect. I've pretty much reverted to 2.4GHz except when I get the urge to test 5GHz out again.

Poor wifi connectivity and speed compared to other devices

My Nokia 7 Plus connects to my Netgear D7000 router on both 2.4Ghz and 5Ghz.
When the phone is near to the router it will max the connection speed out using speedtest at about 75mbps (max internet speed for me) however as the distance from the router increases the speeds drop off dramatically to either 1 or 2 mbps or they drop completely and it keeps trying to jump between networks presumably because the signal is low.
The drop in speeds seems to affect the download speed more than the upload speed.
I have an old Galaxy S5 and in the same positions it holds the connection easily and will still max the connection. I can go much, much further from the router before the connection drops.
If I use wifi analyser then I see that on the S5 the signal looks to be about 10db better, it simply looks like a case of the S5 having better reception.
How do others find the performance compared to other phones, is the wifi poor or do I have a duff one?
I'm currently using Oreo 8.1 with the July security update., has anyone noticed wifi being better using Android P?

Android p is far better

Thanks for the quick reply.
I'm just reading through the thread on Android P at the moment and will probably give it a try providing I can make sure I can roll back to Oreo easily so the device can be returned if it is actually faulty.
