Semi-scientific benchmark of UMTS/HSDPA PC Card vs. Tethered

Ok, so it looks like I was bored, and so far I haven't seen anybody else try this so why not, right?
As the owner of a Sierra Wireless AirCard 860 (UMTS/HSDPA) and an HTC TyTN (UMTS/HSDPA), I figured I could be the first to compare different types of PC data connections.
Anecdotally, it seemed like the TyTN USB-tethered connection was roughly the same speed as the direct PC-Card connection, and the TyTN tethered over Bluetooth definitely seemed slower, but it was time to confirm.
For all tests, I used Cingular's ISP.CINGULAR APN, and I logged in as [email protected]. There was no proxy server used at all. Also, I disabled all apps on my PC that might try and hijack the data connection and disconnected WiFi and wired ethernet connections before getting started.
For my benchmark, I ran the 600k test from DSLReports.com
Finally, all tests were run within a 45-minute period at my home office desk in the Boston area (I had a good 3G connection for all tests).
So the results:
Siera Aircard 860
11:25pm 634 kbs
11:26pm 559 kbs
11:27pm 651 kbs
11:28pm 737 kbs
11:29pm 646 kbs
-----------------
Avg: 645 kbs
HTC TyTN (USB Tether)
11:41pm 585 kbs
11:42pm 737 kbs
11:43pm 748 kbs
11:44pm 648 kbs
11:45pm 520 kbs
-----------------
Avg: 648 kbs
HTC TyTN (Bluetooth 1.2 Tether)
12:06am 307 kbs
12:08am 296 kbs
12:09am 312 kbs
12:10am 275 kbs
12:11am 308 kbs
-----------------
Avg: 300 kbs
So what did I learn from all this? Statistically, there was no difference in speed between the PC-Card and the Tethered USB connections. Also, as expected, the Bluetooth connection was significantly slower.
Other conclusion: I really can't justify keeping the PC-Card 3G plan anymore! I'll be giving up simultaneous Internet-on-PC and phone connectivity, but at a $59.99/mo savings? I think it's worth it!

What about using a Bluetooth 2.0 adapter on the PC?

I didn't have a BT 2.0 card to test with, but I doubt it will make any difference -- the TyTN doesn't support EDR...
I should also note that I've seen significantly higher speeds than reported in the test, but this is pretty indicative of how the different configurations behave.
I've cancelled my data card plan effective 9/25. If somebody wants to lend me a card between now and then, I'm happy to try it...

Low Wi-Fi speed on LAN

I've noticed the following problem:
When trying to download (file copy/video play) from my LAN to the HD, download speeds maximum is about 340 kbps (LOL...that's like EDGE) . With the same setup (wireless "G" router) I can download on the HD from internet with speeds 2 000+ kbps. LAN operations between my PCs/laptops are @ 60 000 kbps wired and 20 000 kbps wireless (using the same setup). To access my LAN from the HD I'm using Resco Explorer....and at that 340 kbps speed it's not possible to watch movies from my LAN. No such problem with my other PDA (iPAQ HX4700) which is not even "G" but "B" device - speed is about 3 000 kbps. Can anyone confirm this and suggest a solution? Can anyone watch movies from LAN encoded with more than 400 kbps?
p.s.: Speeds are measured using DU Meter (for PC)
p.s. 2: Same low (340 kbps) speed with another wireless router

if you are using the default memory card that came with the phone, it is only a class 2. the write speed isn't spectacular, this may not be the reason. but it's the only variable i see right now. since your can download stuff to your phone from web at good speeds. i think it's more of a problem with the machine that is "uploading" or hosting the video. check the upload speed of that machine.

I think the memory has nothing to do with the problem. And I've tried with different host machines - the same result.

Slow network speed through WIFI
I have to same problems on my HD. I am using a home server at home which holds all of my videos. When connecting to it and watching a video with my old Eten X800 everything works fine and runs smoothly. But doing the same on my HD results in an unwatchable video. If I copy and paste this video on my mem card on the HD the video runs smoothly. There are some strange things going on with the WIFI speeds on the HD
Anyone worth investigating this issue?

Yeah... the strange thing is LAN speed is much lower than Internet speed using same network equipment

The Host could be PC/another PC/Laptop - the results concerning the HD are identical, which means the problem is not from the Host nor the network setup.

Did you check the power saving settings in the WiFi parameters ?

YEAH!
it could be toggled/switched on "better performance" for better speed and "best performance" for g protocol. But the device will be hotter!

These settings affect both Internet and LAN performances but Internet speed is OK and LAN speed is slow. And yes, I did play with the settings - results are the same. (because I'm 2-3 meters away from the wireless router). I'll be glad if someone with HD, actually tests a connection between his HD and a PC in a LAN and not just giving "blind" suggestions. What I want to know is if it's a problem with all HDs or just my device is faulty.

the nerd in me just want to go to your house and troubleshoot this for you in person. LOL... anyway...
what is the file you used to test in each case? the reason i'm asking is that some files are more compressed than others, and the speed we see is the NOT the raw speed -- the capability of the wifi card. but the combined speed of the CPU processing power and the network speed.
long story short, if you are downloading, the data is broken up and transfered piece by piece -- a movie is broken up and transfered bit by bit. depending on the file, the receiver side needs to process these bits and recombine them back together. it's much easyer to recombine a webpage, text file or equivalent. but mp3s, rar/zip or movies are already compressed/encoded with special algorithm, so the receiver processor needs to chew through these data to recombine them, so it won't accept faster than it can "chew".
of course this may not be the reason for your problem at all, but try transferring a large text file (copy and paste text from a website to notepad and c+p over and over, till you have a ~ 10MB txt file).

Even on copy files (not trying to play them, hence no decompression) just copy from PC to HD, no matter what the file type is, the speed is that - 340 kbps. Why don't you just try it yourself?

Does it really improve speed? I find WIFI a bit slower with the yweak installed.

With my HD the same slow speeds. Tried several different hardware. Only HD is slow as hell. WIFI speed tweak does'nt do much, btw.
Some speed results:
WIFI Setting Best Battery / Resco Explorer 7.05: 45 KB/s
WIFI Setting Best Performance / Resco Explorer 7.05: 300 KB/s
WIFI Setting Best Performance / Total Commander/CE v2.51: 600 KB/s
So Resco does not work well with local shares. won't be using that anymore when c/p'ing. Altough speeds are doubling with TC it still is'nt fast imho.
Noone else tried this and encountered the same problem?
Ever find a fix for this?

I noticed the exact same problem last night when trying to play some TV shows over Wi-Fi from my PC. The file played OK for a couple seconds, then stalled
Using "Network Plugin for File Explorer" from HTC, I get an ave. speed of ±340kbps. The speed is the same whether I save to memery MC or phone memory. So the write speed of the MC has no bearing on the problem.
PS. Just tried on my work network with the same results...

Lucky you guys... I at best performance get ~120kb transfer and at optimal I get ~80kb transfer (copy) with Resco on wrt54gl with ddwrt on it

USB Tethering on Linux problem solved

I've had an issue tethering my WinMo 6.5 Energy ROM on an HTC Fuze with Linux. The connection itself was fine but browsing was flaky. Some sites worked while others did not.
I finally tracked it down to an MTU problem. You basically need to reduce your MTU size to get it to work (the lower the MTU size, the more packet overhead and hence lower effective throughput). The default MTU size was 1478, reducing it to 1200 solved the issues I was having. If your phone is connected as eth1, the command to change it is:
ifconfig eth1 mtu 1200

[Q] Any way to change WiFi transmit power on Nexus 4?

I've downloaded apps that claim to be able to change the WiFi transmit power, but they all required the iwconfig command to be available on the phone. Is there any way to change the WiFi transmit power on my Nexus 4?
I would like to lower the transmit power to the absolute minimum so I can have the WiFi hotspot on more often without it draining battery so much.

up

WCNSS_qcom_cfg.ini in system/etc/wifi,
maximum tx power
gtxpowercap=30
tried editing the config file?, i dont know if it will work, maybe have powercap=10

I find a way to verify if it works:
Turn on virtual router in windows, use Microsoft Network Monitor to capture wifi traffic, after it have connected, click an Association Request frame in a capture of Network Monitor, in the Frame Details window, expand nodes and note the value next to the node labeled MaximumTransmitPowerCapability:
Frame: Number = 9, Captured Frame Length = 193, MediaType = WiFi
- WiFi: [ ManagementAssociation request] ....... RSSI = -26 dBm, Rate = 6.0 Mbps, SSID = Router14

slow tether with usb

hi
any one know how to speed up mobile usb tether
speed on computer never get a test past 1mb up
http://www.speedtest.net/result/6499841208.png
on phone i get 7 up 3 down
has the dash cable someting to do with it

I’ve got the same problem. I verified it’s the device by putting the sim in a z5 compact. Upload is fine it’s just download that stalls over usb tether. I have also tried 4 different usb cables
It seems like a problem with the device or software itself.

Finally I have found someone with the same problem. Well kind of. I find the usb tether works fine on windows. However the download is slow on all flavors of linux I have tested. That is Opensuse, Fedora, Mint, and Ubuntu. I'm using a dual boot notebook, so the windows 7 pro operation is on the same hardware.
The problem is framing errors. About a third of the packets need to be sent again. On linux, run ifconfig. Your USB tether should be usb0. You will see errors on the RX line.

Yikes, I'm having the same (on Fedora, if this matters). Wifi hotspot is fast, USB, not so much.

Thanks. It has been like pulling teeth to get anyone to try to duplicate this problem. I mean really, is a linux user tethering a OP5 on USB that much of a unicorn????
I will now reopen my ticket with OnePlus that the problem has been reproduced.
Thanks again.

I got the same issue with mint with USB
Without drivers Windows doesn't Work fine too

It wouldn't hurt to open a ticket with OnePlus. Let them know it isn't an isolated incident. Include the ifconfig output.

Any news on this?

they told me do a factory :silly: reset
havent tried it yet

I have -- did a reset on Saturday. Will test soon and report back to you.

Been through all the available options:
* Unrooted stock Oxygen OS
* Rooted FreedomOS
* Rooted OxygenOS
* Custom ROMS like Resurrection Remix
Always doing a completely clean flash, wiping all partitions and restoring user data with TitaniumBackup.
USB tethering is completely b0rken, period.
This is both with Fedora 26 and OpenSUSE Tumbleweed, can't say about Windows, don't have any version of it up to date.
It's highly annoying since this is my fallback for my sometimes flaky 4G home ISP. WiFi tethering is fine, but especially for high quality streams and ssh/sshfs connections to my own server I'd like to have bandwidth very low latency. Maybe it's a modem firmware problem?

run ifconfig
any thing similar in windows
ipconfg dose not give much

I want to buy one of these OnePlus 5 bad boys but I do not see anyone doing a 6.01 Marshmallow and near as I been able to tell 7 Nuggets screwed over all tethering in all forms.
I used it on my samsung s7 and beyond tethering 7.1.1 was very glitchy messy Experience for me that left a very bad taste in my mouth.
My plan allows tethering and I never got higher than 10 kb with 7.1.1.. Reflashed and it fixed it for hot spot but the usb stopped completely ...
7.1.1 a mess and its not the Device Model but 7 Nugget based Roms...
So any word on a Custom Based 6.01 Rom ?

All I got from OnePlus was acknowledgement that my ticket was open again. Also they wanted to know that I was running the latest OS. Nothing beyond that.

I tried again after factory reset and it's still the same, max 200Kbps

Hi all,
Got feedback from OnePlus, they've instructed me to downgrade to 4.5.8. Is there anyone running 4.5.8 by any chance?
Also, I've tested Windows as well and it's fast. It's only slow on Linux.

had same problem in 4.5.8

any one get this fixed ??

Not yet. I'll poke the guys at the ticket again
