2 K/bytes download speed on T-Mobile UK

2K/bytes download speed on T-Mobile UK
Using the speedtest.net app I'm only receiving 2 K/bytes download speed and an impressive 134 K/bytes upload.
There is nothing in the background using the Internet
Full signal strength/bars
APNs correctly setup on device (general.t-mobile.uk, username: t-mobile, pass: tm)
Have free 3GB Internet Booster on the account
Content filter removed
Capped data rate removed
Connecting by WiFi at home receives 1174.2 K/bytes down, 137.2 K/bytes up
I'm absolutely lost at what could be the fault. Called T-Mobile mobile tech support team and they say there's nothing wrong with my account or known issues with my area code, and my signal strength is top.
Sometimes I get 40 K/bytes max (very rare but possible)
Any ideas?

Test your SIM in another phone and see if that makes a difference.
If it doesnt then do 5 speed tests throughout the day noting the time and results and the postcode your in and call tech support and ask them to escalate it to the network guys

I've just tested my connection and got 247kbps download and 121kbps upload.
That's using the same app on T-Mobile, and I don't live in a city (though the speed results when I had my G1 were worse when I went into Newcastle).
Have you tried the speed test when your phone is closer to a different broadcast tower? That would be the easiest way to tell if it's your phone or the local network.

Thanks for your comments guys. I've just run the speed test at my work location in Slough (inside the office, much slower... I'm guessing because of the thick brick walls and loads amount of local networks and electrical equippment around)
Down: ranging from 76 to 133.7 KB/s
Up: ranging from 54 to 57.9 KB/s
Signal strength: poor (1 to 2 bars) ranging from -99db to -105, 7 to 3 asu
So it's faster at work with only 1 bar, how does that work?
I also tested it this morning in my home area (where I'm having the problems) and again it's 1-2 KB/s download speed but fast upload with full bars.

Checking this morning I'm getting 600kbps down/450kbps up on T-Mobile, 2 bars HSDPA.
This is quite low for my download speed, as I'm often getting 1.5mbps+.
If you are getting a problem in a specific location, chances are it is the cell tower.

Dave

I honestly don't know how you're getting those speeds. Top speed I've seen on my HTC Desire on T-Mobile is 150 KB/s

It should be very achievable as long as you are connected to a cell via HSDPA, and the cell has sufficient capacity. Bear in mind that cell congestion can cause your speed to vary wildly during the day.
I presume that you have an H on your phone when you are testing?

Dave

Looks like there is an issue on your home transmitter do what I said with the speed tests at intervals and get them to escalate it

My handset shows the HSDPA symbol. Even during non-peak hrs like 3am it's still slow. Occasionally it spikes up to as high as 40KB/s but 9 times out of 10 its no faster than 2KB. Tried the sim in a friends HTC Hero and get the same result, if not around 30% slower (expected as this is a slower device than my Desire)

Just tried it on my phone and got a d/l of 1045 and u/l of 489. This is a bit slower than I normally get as I have full reception although it has thrown up a bit of a teaser as when I did the wifi speed check I was only getting 1.8 mbs where I am normally nearer 6 mbs

Wifi 802.11n limited to 65Mbps max?

I've stumbled across a number of postings that mentioned people get a maximum throughput of 65Mbps with the Wifi N mode on the Desire. That would make sense as it likely only utilizes 2.4GHz with limited internal antenna capabilities.
What it also means is that 802.11n is pretty pointless compared to 802.11g which already provides data rates of 54Mbps, and reportedly consumes less battery power.
It was also reported that the official Froyo release already activated 802.11n mode, which would make further modifications unnecessary.
My questions in the interest of throwing anything related to 802.11n out of the ROM:
1) does Froyo indeed include N support? (I don't have a N router and can not test it)
2) is N indeed limited to a max data rate of only 65 Mbps on the Desire?
Thanks for reading and hopefully feedback

I have an 802.11n router and gets a max of only 65 mbps transfer rate using Froyo. I have since disabled N support on my Desire to save some batt life.

Using Pays Froyo 1.9 with enabled N and connecting up to 72Mb/s.

Not sure about anyone else, but with 802.11g the phone will connect at roughly half signal to my router, speeds of about 20-25mbps, when i connect via 802.11n the signal is much better and it connect at full 65mbps, though yeah i never get above 65mbps, i think this has to do with the antenna arangement, 802.11n had 3 antennas, and i think the desire only has 1 so the total speed is limited

i´m more interrested in the speed you transfer with on the diffrent modes since i get less than 20Mbit with G from local to local.. and i wonder if i sould invest in N ? does it give higher transferrates ? eg the speed of the filetransfer between comps..

sorry to ask
sorry to ask a noob question, but where again do you check to see the speed of your wireless, I did it once but can't remember how.

Phone *#*#4636#*#*. As to higher WiFi N speeds. We won't get higher speeds that 65-72Mbps because WiFi N mostly operates on the 5GHz band.

what a brainfuck 802.11 works with up to 600mbps at 2.4 ghz like on 5 ghz
. i wrote exams about wifi.
i bet the desire uses 1 antenna so it can get a max of 150mbps symbol rate.
but i think it uses a channel bandwidth of 20 mhz instead of 40 mhz so it is limited to the half of 150!!!

Well im currently connected at 72 using LeeDroid

ye this just shows your connected speed..
to get the actual speed you need to transfer a file between computers locally.
those 2 speeds vary alot since it depends on noise and interferrence and loss.

OK, that explains it. So we have a physical limit here for the throughput.
How about the better signal strength for N? This may be the result of the coding scheme. And more importantly, does the stock Froyo already provide 802.11n, so we could get rid of all the firmware and module hacks?

Bongmaster is right, you have different speeds for wireless N devices.
The desire is 1T1R (1 transmitter 1 receiver), and therefore can only only get 150mbps as a max theoretical speed. 2T2R is required for 300mbps operation.
However as mentioned, this only works with 40mhz channel bandwidth, 20mhz will cut it in half again.
Can someone force 40mhz channel bandwidth on their router and post results? Most Wireless N routers seem to come with 20mhz as the default setting.

Let me bump this again, there is one important question that was not answered yet:
Does the stock Froyo release (OTA) support Wifi 802.11n or not? I can not test it as I don't have access to a N router.
Thanks!

Everything I have read says yes.

I did this and it made no difference, 72Mbps was the maximum it showed.
To be honest, I'm not sure the Desire is even capable of handling anywhere near this speed anyway. When connected to my home wireless at this speed, the actually download speed I get via speedtest.net is somewhere around 15-20Mbps and I have a 50Mbit connection.

Don't know what's up with all yours but mine is running at 425.9 MBPS.. IT is lightening fast, much faster than my 128mbps stick.

That's all your getting from your ISP then when you tested, try it again at 2am or something when there's less people in your area sharing your bandwidth.

Wireless N 2.4Ghz @ 65Mbps

So I've been messing around with my router and checking transfer rates to see if everything is working as it should. I have the Linksys WRT160Nv3 router. I noticed that my Nexus was only connecting at 65Mbps while my laptop shows a connection of 150Mbps. I have my router set to N-Only, WPA2-AES, and 40Mhz channel width. Is the Nexus limited to a 20Mhz channel width? Is anyone else getting connection rates above 65Mbps?

Seems to be normal from what I gather. Don't know if these phone are capable of processing that much data anyways. I'm not sure how fast the NAND storage is but it seems to top about 10 MB/s which is about 80 Mb/s I think. Really not much point in connecting faster. Very few people have access to those speeds anyways, even lte users. If the phone has sd cards it would be great. I have a lexar micro sd that can write 20 MB + a second.

SM-T700 Theoretical WiFi speeed (2.4G/5G)

Hello,
Does anyone know the theoretical WiFi speed of the SM-T700 in 2.5G and 5G band? Or can someone share his?
Using OOKLA Speedtast, I'm having approx 8-10Mbps under 5Ghz band with mine (similar perf w/ file transfer from a computer on local computer) but I get 40-50Mbps with other connected devices (eg S7E).
I'm not sure if this is due to device capability or ROM issue, so I'd like to know what is to be expected first.
Thanks for your input.

The 802.11AC, which works in the 5GHz bands, gives roughly 100Mbps per stream for a 20MHz wide channel. The Tab S supports two steams and up to 80MHz wide channels, so in theory with the right access point setup, you have theoretical speed of 800-900Mbps. However, in real life wi-fi wastes at least half of its bandwidth on it's own protocols house keeping. So the Tab S should be able to have 200-400Mbps ish link to the router under the optimal conditions. However, the 5GHz band slows down tremendously with the distance or behind the walls. If you're not getting 50Mbps in the speed test, then you're probably far away from the wireless access point, or there is some kind of interference going on. The 2.4GHz band is slower and usually more congested, but it reaches greater distances.

Thanks for the details @Akopps.
From what I observed, the max download speed on my Tab S is averaging 7MBps whereas using my laptop I get at least 20MBps. Same distance from router, located <4m and 2.5m up without obstructions.
So its seems I'm way below theoretical capable speeds but unsure why.

Fastest WiFi speed?

Hello,
I have just switched fiber provider at my place (FTTH) and I am now getting a whopping 1000 Mbps on my connection via gigabit ethernet.
My ISPs internet "box" luckily comes with 4 gigabit ports but only 2.4 Ghz WiFi (...). Which means that what actually reaches my portable devices is somewhere between 20 to 70 mbps, depending on my location in the house.
So, I ordered a Netgear R6220 to connect to my ISPs box, whose WiFi I will disable, hoping to get the most out of my fiber connection.
I see that this router supports simultenous Dual Band (300 + 867) which should exceed my ISPs downstream bitrate. But I wonder whether the 835 on my P2XL will be able to benefit from the simultaneous Dual Band transmission.
According to the specs it should (https://www.qualcomm.com/products/snapdragon-835-mobile-platform):
Wi-Fi
Wi-Fi Standards: 802.11ad, 802.11ac Wave 2, 802.11a/b/g, 802.11n
Wi-Fi Spectral Bands: 2.4 GHz, 5 GHz, 60 GHz
Peak speed: 867 Mbps
Channel Utilization: 20/40/80 MHz
MIMO Configuration: 2x2 (2-stream)
Peak QAM: 256 QAM
Wi-Fi Features: MU-MIMO, Multi-gigabit Wi-Fi, Dual-band simultaneous (DBS), Integrated baseband
Click to expand...
Click to collapse
But since the Peak speed is listed as 867 mbps, I'm not sure...
Anyone was ever able to max out the P2XLs WiFi speed?
Thanks!

This is mine today, I have seen higher from my wifi but this is right now.

This is the best speed i got using the 2XL
1Gbit line using a Asus RT-AX88U router.

Wow, this is impressive! I didn't think our Pixels could reach that level of performance!
I guess that the bottleneck for me will still be on the router, then, since I'm not getting anything quite like yours (smaller budget).
I'm getting from Amazon an R6220 and a couple of Tp Links (archer c7 - 1750 and archer c1200), the best one gets to stay! ?

You should be able to reach decent speeds with any of those routers the only reason I bought this one is so i don't need to buy another rooter any time soon.
