[Q] Can a Nook do better than 54 mbps Connection

Wondering if there is anything that can be done to get a Nook to connect at faster than 54 mbps G speeds? Does it really have a N wireless chip? I have searched and searched and cant find an answer to this.

According to the spec sheet, the wireless radio chip does support N. I'm not sure whether the software supports it
Radio: Chip ID Ti wl1271 (kernel reports wl1273) Chip supports bluetooth transmit/recieve and fm radio functions through the same antenna, but is not enabled in software drivers. Connectivity: 802.11b/g/n Security: WEP/WPA/WPA2/802.1x Mode: Infrastructure

I get N connectivity via CM7 - been so long since I ran stock that I don't recall.

Yamadog, do you currently have a n router that you are trying to connect too?
I've read before that the Nook Color wifi chip only supports 2.4 GHz range (which is used for both 11g and 11n) but not 5 GHz range (which is only for 11n). If you have a b/g/n/ router running in compatibility mode for all three types then it might possibly be doing 11n only at 5 GHz and 11b/g only at 2.4 GHz and so your Nook would never be able to see the 11n signal. Try putting your router in 11n-only mode and see what happens

I'm on CM7 and I've never seen a rate above 54mbps regardless of N availability.

I have no problem with the connection its just it connects at only 54 mbps which limits download speeds to around 11 mbps Max. My computers connect at 270 to300 mbps at download at my full 24 mbps speeds. I did have a g only router and it limited my computers to only 11 mbps like the nook. Aipparently the g rating of 54 mbps is just under ideal lab conditions and not really obtainable.

According to my home N router, the Nook Color connects at 54mbps but N is in use. For some reason that is the max rate it will use. I've seen this happen with other N devices when WMM is disabled on the client.

Whoa sorry never really answered you. My router is a cheapo 2.4 ghz n but it does allow 300 mbps connections. I have to run it in b,g,n mode because our wii is only g wifi.

I bet that's the case with mine too, but I haven't checked. It does pick up signals like its running n though.

802.11n operates on both 2.4GHz (20MHz bandwidth) and 5GHz (40MHz bandwidth).
Anyway, how do you guys check out the rate on the NC?

I know, but I've heard of routers that do compatibility mode by segregating g and n between the 2.4 and 5 GHz antennas

Didnt realize all n routers did this. Checked mine and it shows my computer on 40 mhz and Nook on 20.
To check Nook connection link speed just click on the connected network and it lists all info for it.

I checked and did not have WMM enabled on my router. Enabled and although the connection speed still says 54 mbps, I recorded much higher, sometimes double, the download speed vs WMM turned off. Thanks! It might be a fluke but the speeds were not far off my desktop.

Actually it is a fluke. All along I have been using the android app for speed test to check my nook and it shows roughly half the speed vs the regular desktop speed page of speed test. Oh well at least I know I'm getting all the speed out of it.

fyi the Wifi chip is capable of up to 65mbps. I've seen this rate from other tablets with TI WLAN chips on my router. I haven't a clue why the Nook Color won't go that high. Not on any N router I've connected to.
I even took a look at the tiwlan.ini file but I don't see anything apparent in there. N appears to be enabled.

[Q] Slow Internet Speed on Wifi Nokia Lumia 1520

I am facing a slow speed using wifi on the lumia 1520. For sure there is something wrong with the wireless card or the drivers.
1. The internet speed while connected to wireless that i get on the 1520 is half or even more less than what i get on my desktop (connected wirelessly) or on my other phones (both being android). I get a 25Mbps download & upload both on the computer as well as on both the android phones. But on the Lumia it will hardly even cross 10Mbps for download and 16 Mbps for upload.
The issue with the speed is really strange because if i connect the phone to a 2.4 Ghz network i get upto 10 Mbps download and 16 Mbps upload speed.But if i connect the phone to a 5 Ghz N network then the download speed i get is 0.67 Mbps and upload 14 Mbps. Whereas both my androids have a download and upload speed of 25 Mbps no matter whether connected to a 2.4 Ghz or 5 Ghz network.
I have changed different channels on the router and have almost everything including resetting the router as well as resetting the phone but no luck. The phone is OOB lumia black OS.
Any ideas anyone.

What router do you have? My internet speed is 55mb down and 6mb up. I get 56 to 58 down and 6 to 7 up on my phone. I have an Asus AC1900 router. This phone has been one of the better phones I have owned when it comes to WiFi speed.

I have a netgear wndr 3700v2 router . I was able to resolve the 0.67 Mbps speed issue on the 5Ghz N channel by enabling WMM on the 5 GHZ channel however still the speeds are half of what is the internet connection speed.
The surprising part is that after enabling WMM the speeds on the note 2 when connected to the 5 Ghz N channel reach the proper internet speed as on a wired ie:- 39 Mbps but on 1520 they hardly cross 15 Mbps download .On the note 2 or my other android as well as my desktop the download and upload speed is proper on both the channels 2.4 as well as 5 Ghz. This indicates tht the router is fine.
I think i have to contact nokia support to have this checked. I am not sure as to what else to apart from this.

Same issue on a N97, wifi is muuuuuuuuuuuuch slower than 3G. Some messages I got about certificates let me suspect the preinstalled Boingo appli. All worked fine on my previous 5730.

G900-F real life WiFi 802.11ac performance benchmarks

Hi all
I couldn’t find detail benchmarks of S5 implementation of Broadcom BCM4354 2x2 MIMO 5G WiFi 802.11ac module and in the end decided to take u plunge and purchased Asus ac68u router. Went thru setting up 5G ac wireless network and current results look like this:
S5 connects to 5G ac network with link speed of 866Mbps
File copy from:
Gigabit LAN wired PC to Routers attached USB 2.0 HDD 29MBps (240Mbps) - bottleneck usb 2.0 interface
5G ac WiFI S5 internal storage to Routers attached USB 2.0 HDD 11 MBps (90Mbps)
5G ac WiFI S5 sandisk 128GB microSD card to Routers attached USB 2.0 HDD 11 MBps (90 Mbps)
I have 100/100Mbps broadband internet connection and S5 on speed test performs as follows:
72Mbps DL / 75Mbps UL (same connection via wired PC benchmarks at 94Mbps DL / 95Mbps UL)
I haven’t managed to achieve transfers speeds above 100Mbps from or to S5 in any combination. Can you please share your experience of S5 wifi ac 5G network performance
Related : thread by xenokc about S5 performance on 802.11ac network
Thanks

can you test with no encryption? wep/wpa completely off.

Yes, i have tried that, but there was no change. Router firmware is upgraded to the latest version / wireless test were done in close proximity (1 meter) to the router without any physical obstacles between (clear line of sight)
I'm really on a mission to achieve transfers speed in a range of 350Mbps-400Mbs on local LAN (which should be doable) but i cannot get pas 100Mbps!!

i'll try to test as i know AC should be able to do it.

802.11 ac provides a theoretical maximum stream speed of 433 Mbps or 900 MB/s across eight streams. That is under ideal conditions - maximum signal strength, zero interference, zero processing overhead and zero packet overhead. Many router 802.11ac chipsets only support four streams and due to real life channel contention, you aren't likely to see more than two or three 160 Mhz channels chopping that maximum speed to about 250 MB/s. All of those speeds assume channel bonding and quite a few routers can't bond 80 Mhz channels cutting that speed in half again (125 MB/s). Then you have real world losses due to signal attenuation, antenna inefficiencies and interference.
The S5 was the first smartphone to support two MIMO streams. But two is not three, so lop another third off our speed figure (or lop two thirds off for the iPhone 6 which only supports one stream). You simply won't achieve your goal with the S5 or any other current smartphone. 350 Mbps is the upper end of the maximum speed you might expect to see from a high end MIMO PC card under ideal conditions in the same room.
In real life and through a wall, you should expect considerably slower transfers. And the type of traffic matters too e.g. TCP traffic overhead often reduces speeds three fold over UDP streams in router speed tests.

Thanks for detailed feedback, but then there is no benefit from implementing ac standard or 2 spatial streams suporrted by broadcom chipset when performance is comperable to WiFi n standard? But then again how did those guys here managed to pull of such results:
382MbpsDL
or
436Mbps
whit same hardware setup?

..

what kind of latency differences did you see between the wifi phone and your pc to the same server? i'm assuming speedtest.net or something like that?

This is strange as for my G900I I've been able to run an Internet speedtest at over 11 MBps (88mbps) over wifi on wireless N at my university which I imagine would have multiple connected devices. Wireless AC should be able to at least match the 88 mbps I had achieved.

No, don't do this. You must setup a WPA2 security encription to get maximum rates on WiFi N and AC.
Then, remove storage bottlenecks. Don't use a external HDD connected to a USB2 port. Much less on the same router, since USB performance is much lower on those devices. You will need to use 2 devices on the same LAN. One wired for maximum throughput tests. A ramdisk or a SSD on the host would help too, since HDDS are limited to 120-80Mb/s transfer speeds.
If you are going to use a file copy as measure, make sure you make it into the internal SD card of the phone, since external will be limited to around 8-12mb writes depending on the card quality.
To test networks you would need ramdisk to ramdisk copies, but I don't know how to setup this on android.

This is rather interesting to follow

iPerf is available on android.
Quick measurement gave me ~110-169 Mbits/sec using default values on 40mhz WiFi N 5ghz setup.

Thumbs up. Finding someone that uses IPERF for measuring proper network performance is golden. It irritates the heck out of me to find video's of people using ookla to measure their network speed, or like the OP, measuring against USB2. That's like measuring the speed of your new 600MB/s SSD installed on a SATA 1 controller and wondering why you are not seeing a significant improvement.

iperf is a little more complex than ookla though, and thats usually why. same reason most of us dont compile our own custom roms
really, there isn't much need to get over 100mbs on wifi for 90% of the public.

Just picked up the s5 because no store will sell me the note 4 retail price.
Linksys WRT1900ac stock firmware, 5Ghz a/c connected @ 300Mbit
From the phone to wired linux box @ 1000Mbit
187 Mbit up 207 Mbit down but of course it fluctuates. I don't use wifi for anything that requires that much bandwidth anyway, but I do get my full internet speed of 175/30 using the phone.

This post is rather old, but some of us may still be interested.
I was looking for an alternative to usb cable to transfer files fast between a pc and galaxy S5..
I've used a wifi-300 stick connected to usb port on PC: TL-wn821N, and configured my S5 as a mobile access point.
An ftp server is running on the phone and an ftp client on PC. i am accessing the AP via AirmoreAP hotspot, with wpa encryption.
I am watching the download rate via crystal internet meter for windows.
And this is the result: 64mbps/56 mbps (DL/UL) UL reading a microsd card on phone and writing to sata2 internal disk on pc.
I am wondering if I can reach much faster speed with a wifi-ac stick.

[Q] Wifi link speed

Hi guys,
Do you know maximum wifi link speeds over 2.4 and 5 ghz?
In my home network with 2.4ghz wifi n I get max 54mbit link, while with the tablet I get 117mbit at the same place (right next to the router).
With 5ghz would I get higher link speed??
Thanks,
Edgar

Low wifi speed

I have noticed that my Mi A2 does not show full speed on wifi.
I have a 100 Mbps connection, which when I connect via my laptop clocks at around 92+ Mbps, but on my A2 it only clocks about 50 Mbps.

Check which type of wifi your router can provide.
From Wikipedia : There are many different versions of Wi-Fi: 802.11a, 802.11b, 802.11g, 802.11n (Wi-Fi 4[40]), 802.11h, 802.11i, 802.11-2007, 802.11-2012, 802.11ac (Wi-Fi 5[40]), 802.11ad, 802.11af, 802.11-2016, 802.11ah, 802.11ai, 802.11aj, 802.11aq, 802.11ax (Wi-Fi 6[40]), 802.11ay.
One of the most popular wifi norm used over the years is the 802.11.g, which is capped at 54 Mbps. Could be an answer.

Just tested at home.
I have a 350 Mbps connection. I get 120 Mbps in download, and 40 Mbps in upload. (can't post pic)
I think my router must use 802.11ad, but I'd have to check.
---------- Post added at 06:53 PM ---------- Previous post was at 06:48 PM ----------
Back again, made more tests.
Be sure to connect to a 5 GHz band. My router can use 2.4 GHz and 5 GHz bands.
I'm getting way worse results on the 2.4 band. So use the 5 GHz if you can.

Either its using 40mhz channel bandwidth (144mbps per "antena") or it has dual antenas (2x 72mbps at 20mhz or 2x 144mbps aka 300mbps at 40mhz).
Mi A2 only has one for 2.4ghz (72mbps at 20mhz or 144 at 40mhz) and one for 5ghz (433mbps at 40mhz and 200ish mbps at 20mhz if im not mistaken)

40mhz is a bad ideia for 2.4GHz since to do it it overlaps channels wich most probably are already in use around you.
on my Mi A2 on 2.4ghz i always get around 50mbps (72 minus overhead) which seems just fine. The phone is fine.
on 5GHz i get my 200mbps.... your laptop probably has MIMO technologie

Ok thank you for the explanation, I'll just upgrade my router, and probably check if I still need the range extender, then maybe upgrade that too

Check your wireless AP? Or try it with another AP?

When i test the speed then in Redmi note 7 pro is always getting 50mbps or below it cannot goes beyond 50mbps but in Realme 5 pro and in my laptop both are getting full speed around 72mbps..
Therefore you all have not any issue with your wifi router the problem is only in your Mi devices....
If you don't trust then check and compare the speed with any mobile and u will get to know the Mi devices is only limited to 50mbps.
I know that i have a alternative option , if i use 5Ghz router and my redmi note 7 pro also support 5GHz but my question is why Mi devices are failed to getting speed on 2.4GHz where all others brand are getting 802.11n speed.

You are not entirely correct. Maybe it is a Redmi throttle because on my Mi X6 my speed runs to around 100Mbps on 2.4Ghz and reaches around 350Mbps on my 5Ghz connection . My internet connection is a 1000Mbps connection but I only achieve that speed on my computer with gigabit ethernet and cat5 cabled connection. Never by WiFi .

Agreee. I have a Xiami MI A2 and I used to get +70 Mbps in 2.4 Ghz and +150 Mbps in 5 Ghz. A couple of days ago I had issues with my router and had to restart it and now I can´t get more than 30 Mbps in both 2.4 and 5 Ghz... but I also got the March security update in the phone so not sure what´s causing the issue. I´m quite sure it´s the phone because other devices perform fine in the network.

you can solve the WiFi speed by using custom kernel Agni for example. Try the different libs to see which work best . But so yes Xiaomi throttled WiFi in newer versions ..custom kernel like agni gives option in aroma to choose another modified or older lib . This will double your speed .

Hey sorry to bump a thread like this, but it seems it's not an issue many persist with as most internet connections are usually below 50Mbps so users don't notice the issue.
I've got a new Redmi Note 11, and along with an old Redmi Note 8 I have, both have limited WiFi speeds on both 2.4G and 5G networks at 48Mbps for some reason.
Your claim that Xiaomi throttled the WiFi in newer versions makes the most sense, so I have a question if you don't mind. Would just going for the latest Agni kernel do for me? I'll be trying to port TWRP to this new phone and see if I can flash the newest Agni, from there is there anything more to do? Will the WiFi speed be back to normal?
