tether speed vs. device speed - Touch Pro CDMA

Have not seen any posts regarding this, so i decided to start my own. Using my phone on its own, i get great dl speeds. when i then tether my phone to my laptop, using both usb and wmwifirouter, my speeds and latency significantly go down the drain. has anyone found anything on this issue? Any help would be appreciated.

It would probably help if you gave some specifics such as, ROM, radio version, software running on the phone, and type of OS you have on your computer. I don't see a difference is speed except that while tethering, I do load pages much faster (due to greater processing power of the computer). I'm running Calkulin's 10/22 23071, radio 1.11.00F, with no additional apps, and tethering on a laptop with xp pro

What's your EVDO speed?

Saw this on ppcgeeks, I was wondering what xda users' speeds were (rev a or not) on their titan...
www.dslreports.com/mspeed (1mb test)
1603k
opera mini
rev a. update
titan, sprint leaked rom
chicago (NW suburbs)
anywhere from 200k to 1200k
in ie
but, i can't seem to run the test again through opera mini, says to fast/unstable, do i need to clear some cache from opera? so many of these tests seem so off, like running from ie vs opera..
can anyone recommend good websites for testing from the phone (non flash) for accurate results?
I did the 1 meg test for the dcd's titan rom 2.0.0 on my Verizon Titan w/Rev A 3.27.00 Radio ROM
911 kbit/sec - 985 kbit/sec
0.293s to 0.198s latency
9.228s to 8.445s d/l time
I am getting 900k or better on a regular basis, same test site. I cant use speedtest.net for whatever reason cause the phone wont load properly.
If anyone is using other speed test sites, let me know.
I get 200 to 900 on Alltell in Springfield Missouri on the stock ROM. My results are all over the board. It bounces up and down plus or minus 300 kbits from one second to the next in the same physical spot. I check it often since it was my reason for switching to Alltel. It seems strange that it supposedly fluctuates so greatly from one second to the next as Im standing still.
Harrisburg, PA
First Run
837kbit/sec

I'm getting around 900k, but those damned lacked of video drivers really kill the fun of EVDO when trying to use web browsers.

I don't know too much about the lack of drivers; but what does the lack of drivers do to hinder the phone / web browsing?
On Telus, using Opera in my building with ****ty reception, 1039 kbit/sec.
0.329s latency
8.129s d/l time.
That is on a1jatt's custom Telus rom on the latest radio 3.27.00
Wow, a restest shows:
1996 kbit/sec.
0.22 latency
4.323s d/l time.
I'm in Ottawa, Ontario.
800-1100kbps
I used the mspeed a couple times but I prefer speakeasy.

You'll need flash

I cant BELIEVE I had forgotten about reinstalling Flash7
thx

Puts a lot of stress on the CPU to have to both load and render the pages. You see the same effect on a PC if you have no video drivers installed.
There's a non-Java test at www.mobilespeedtest.com. With ROM version 2.09 and only PIE running, I got top EVDO speeds around 955kbps when testing five times in a row, with an average of about 865k when throwing out the one-time 245k result.

[Q] Hardware acceleration, USB transfer speeds?

Just bought the TF201 and I'm absolutely in love, after reading some of the horror stories, I was cautiously optimistic to take the plunge, but I have a C1 model with ZERO lightbleed, great Wi-Fi, GPS is faster than on my Nexus S indoors, and my bluetooth headphones work great without touching the wifi.
That being said, I have a couple of questions:
1. Since Twitter and Facebook apps don't run all that smoothly, (I'm attributing this to their lack of optimization for tablets) I went into the developer options to check off the option for "force GPU rendering" which really helped, it's buttery smooth now, but the warning said that it could slow down my tablet, yadda, yadda, will this option pose any kind of problem? It hasn't thus far on my Nexus S which is running the latest version of Cyber-GRMOD but I don't know if it makes a difference what with this being a tablet.
2. Am I the only one who gets RIDICULOUSLY slow transfer speeds on this thing? I mean accepting defeat that I can't sync all my songs (about 15 gb) from iTunes onto the tablet, I synced about 300 songs through WMP which took about an hour, whereas it takes about ten minutes to transfer that many onto my phone.
Sorry if this doesn't fall into the rules or regulations, but I figured if it's q&a and 98% of these forums are filled with Wifi and gps Issues, I'd turn here to ask.
Glad you got an issue free prime.
1. Force GPU Rendering shouldn't pose any problem for newer apps, but some old apps may randomly crash and not work as expected. If you don't see any issues with the apps you are using, than it should be ok to keep it turned on. You will experience a faster battery drain and higher memory usage though.
Also note that, all newer apps and games use GPU rendering by default regardless of this setting, so once developers release the newer versions of their app you wont need to set this option in the settings. This will be desirable, as turning it off will give you longer battery and less memory usage.
2. The USB connection is quite fast, if you are having slower connections try setting the ASUS PC Sync off (Settings > Account & Sync). Also make sure you are using a USB 2.0 port in your computer and dont have any antivirus or other software scanning the Prime.

Nope. It's generally considered to be the fault of MTP.
You can try Samba Fileserving and transfer files over Wifi. That might be faster. Another solution, which I haven't tried yet, might be Android Commander.
I've been using Swiftp on my prime with filezilla on my laptop. Seems to be more reliable and faster. I have a mac and Android file transfer kinda sucks.

bluetooth file transfer very slow

trasnfered a file from my pc running vista onto my sony tablet s on stock ics
it took ages
almost 20 min for a 10 mb file
is it that slow normally
is there any way of speeding it up
thanks

From the Sony Tablet Help Guide:
"If both the Bluetooth function and the 2.4 GHz Wi-Fi function of your tablet device are enabled, interference may occur and cause
slower data transfer speeds or other problems."
Try turning off the tablet's Wi-Fi to see if that will increase the Bluetooth file transfer speed.
It's probably not usually that slow, but Bluetooth file transfers are an inherently slow process. BT is made for ease of use, decent range and easy interoperability with other devices such as headsets, so it's not really made for fast OTA binary transfers.
As Cat mentioned, try turning off the WiFi to reduce interference and make sure there are no microwaves operating in the area. They mess with practically anything wireless.

Removing the downgraded speed on hotspot

I'm in the USofA using Tmobile as my carrier. When I activate the hotspot on my phone (Note 9) and then connect my non-cellular tablet via the hotspot/wifi, the speed is only like 256kbps (not sure if its KBPS or KbPs or whatever), its just not as fast as the phone is when it's just the phone. The performance is adequate for minor gaming (Hayday) or low res YouTube videos (haven't tried Netflix). Being a new member here and recently learning about custom roms and so forth, it got me thinking the tethering/throttling has got to be a setting of some kind so I thought I'd ask here, Is there a way to disable the throttling of the attached tablet when the phone is acting as a hotspot? :fingers-crossed:

Slow WiFI connection from the Nokia 7.2 compared to the 5.1 Plus

Hi, I have 2 brand new Nokia 7.2 and an old (my previous phone) Nokia 5.1 Plus, and I have a problem that it's freaking me out. The issue is very simple, I almost cannot navigate while using a WiFi connection in my main Nokia 7.2, I have to use the mobile data connection so I can watch a video without any lag or resolution issue but that is not ideal.
So, I perform some test and I find out that my 7.2 does have like 50% of speed from WiFi (both in 5GHz and 2.4GHz) compared to the 5.1, and I'm not talking about external speed test, but in LAN (between my phone connected by WiFi, and my computer connected by gigabit ethernet) using iperf3.
After testing I got this results:
(Result's format: '-Band: AVG Speed (Min Speed -> Max Speed)')
Nokia 5.1 Plus:
-5GHz: 241Mbps AVG (214Mbps -> 252Mbps)
-2.4GHz: 41Mbps AVG (31.5Mbps -> 53.1Mbps)
Nokia 7.2 (both):
-5GHz: 116Mbps AVG (85.9Mbps -> 140Mbps)
-2.4Ghz*: 24.3Mbps AVG (18.5Mbps -> 29.2Mbps)
* I did perform like 3 tests in this case, and those numbers are from the best result. The worst result was like 15.6Mbps AVG
And that is not all. The setup is all the same. Same wireless router (I have 2, and I always check that both phone are connected to the best one), same phone position (like 0.5 meters away from the router, even less), the computer (server) is not doing anything that could use the network card or the CPU, and of course testing one phone first then the other one, and then doing the same but swiping the order. Also both phones (5.1 Plus and my main 7.2) show that have the same link speed (433Mbps) and both phones have Android 9 (Android 10 is not here yet).
The only difference between the 5.1 and the 7.2 is that the 5.1 has 802.11a while the 7.2 doesn't, but the issue about that is that standard is for 5GHz (and it's just for 54Mbps), so I don't think that this is the issue, because that should mean that the 2.4GHz's speed should be the same.
Also, is not like a hardware malfunction beacuse, as I said before, I did the same test with both 7.2 that I have and both have exactly the same issue.
I want to know if anyone has (or had) the same issue. I think that this could be a mis-setting or another battery saver package included in the OS limitating the speed just like when 5.1 had a battery saver that limitates the Background processes
Hi. I didn't experience as much as you did but I can confirm the phone is pretty slow on WiFi. My friend's Samsung J7 loads videos easily while mine gets stuck on buffering for eternity. I looked for this problem on Nokia Forums but I couldn't find anyone experiencing it beside me. I did read somewhere that forgetting your network and adding it again might solve it. I know, it doesn't make any sense and I might be delusional but I think the speed is a bit better now!
Anyway, I still believe there's a problem regarding WiFi speed on this phone. Perhaps it's a software thing just like you said. Anyone else who can provide an explanation of some kind?
