I am supposedly in a UTMS/HSDPA zone (Detroit MI). The phone show me a "U" in the status bar. I've read the speed is around 1.5Mb/s. But I am getting only 30KB/s - 50KB/s MAX using the Hermes as a bluetooth modem! This sucks!
Is this speed limited by bluetooth? If I use the phone as a USB modem instead, does that increase the speed significantly? It's a much more involved setup to do this however.
Or am I missing something? These speeds are atrociuos for what I am paying. I expect MUCH MUCH higher speeds. Please someone enlighten me or I am going to cancel the stupid service.
Very frustrated. Thanks for any input.
Anyone?
I have the same problem via USB, here 60 miles north of Manila, Philippines. Best I can figure, it has to do with the radio stack being used...? I am using Orange m3100, but my buddies in Manila using Dopod 838 Pro and/or Universal, get real 3G speeds with no special settings...
What version of BT is on your laptop? Older versions than 2.0 are very slow. I use USB and get 700 Kbps avg with 2 bars of UMTS in Bay area, CA.
anubus12 - partly the answer gave you Chirunavvutho. Check what kind of BT adapter you have in your computer, which version.
Go to http://en.wikipedia.org/wiki/Bluetooth for details about versions and about speeds.
But, in my opinion and my practice BT option is much slower then USB connection. First of all all interference with other radios (especially WiFi [same bandwith], and other apliences like CRT monitors and TV, microwave ovens even fridge - it sounds weird but they do interfere.
Second - when your device has to be like a midleman, and has to use GSM/WCDMA radio to get information and then send it by BT radio it will limit it's speed. Actually both speed end efficency. That is why it is better to use USB.
Third - I do not know which version of HSDPA has Cingular in your area. Remember that even if they have 3.6 Mbps speeds may be much lower, due to many reasons - lot of users, kloged backbone etc.
Forth - for info on HSDPA go to: http://en.wikipedia.org/wiki/HSDPA
drummer10630 - find out FieldTest_157 here on xda-developers. It is monitoring application for Hermes. Find if you have HSDPA in your area. Remember that pure UMTS (WCDMA) has only 384 kbps. This app will tell you what kind of connection you have. You have here also manual if you do not know what to look for.
Hope this helps you guys
No EDR
The Hermes/TyTN supports Bluetooth 2.0 but not EDR. The maximum speed is 721 kbit/s, or about 90 kbyte/s.

My buddy has a PCMCIA Card with EVDO Rev0. I put it the same computer and got constant DL rates at around 100Kb/s. That is very acceptable.
Using BT 2.0, it's horrible. I don't get anywhere close to 90Kb/sec.
So now, it might make more sense that USB would yield higher download rates. MAYBE.

Thank you very much for the clarification. I'll check USB out to see if the x-fer rate is faster.
As to FiedlTest_157, I downloaded the manual and can't really make heads or tails of how to read it. The manual gives you some parameters, but how do I know what type of connection I have? UTMS/HSDPDA or EDGE?
anubus12 - let me tell you few things and then I will answer your questions. OK?
If you want to have fast data access for your PC - use PCMCIA cards or build in systems - IBM has few notebooks with it, other I do not care
I can assure you that it will be quicker then any connection via USB/BT because hardware and software (drivers and apps) are dedicated only to handle DUN (dial up networking).
So there is no point of comparing PCMCIA cards to PocketPC telephones. Especially when you are using two different networks.
I had HTC Apache in Sprint and Hermes in T-Mobile/Cingular and then I can tell you that Sprint network is simply faster then Cingular. First of all Sprint in my area is fully EVDO-Rev.0 and Cingular is UMTS sometimes HSDPA or EDGE depends on radio used, interference, or even air (windy/raining/t-storm - it has some influence).
HTC Hermes just like other PocketPC handles DUN well, but it is more like backup connection, not when you need it all the time. Just get the info and finish connection. Not because price per MB but they were not build to work this way. You need PCMCIA cards for that purpose (constant net access).
Most of people here might disagree but if you are not traveling internationally on regular basis - use Sprint or Verizon - it is faster and more reliable. Sorry guys its the truth.
When T-Mobile will start 3G it might be different thou T-Mobile has expirence in other countries but other networks has this advantage.
If you traver internationally then you have to use Cingular or T-Mobile. For corporate use I would choose Cingular for personal T-Mobile.
My point is that you cannot compare something which is not comperable. Back to your questions.

OK, let me put it in the easy way
You have Cingular so your only choice is UMTS/HSDPA (3G) and EDGE (2G) because Cingular claims that it's network is fully EDGE enabled.
When on top screen bar you have G (or when using aku 3.3 - E) you are going to GSM (for basic data), AMR (for speach codecs), GPRS (for data connection).
When on top screen bar you have U (or when using aku 3.3 U or H) you are going to WCDMA (for basic data) or HSDPA CQI Status (for knowledge is HSDPA is in use). Well if you see H (aku 3.3) you know that you are in HSDPA area. But if you are using aku 2.3 you are going to HSDPA CQI Status.
You have to know that GSM/GPRS/EDGE data are time and usage driven due to it is TDMA network (Time Division Multiple Access). It means that network data are given to you every few seconds. Because data transfers it is usage then when you are finished data is 0 because nothing is happening. You have to monitor during transfer.
UMTS/HSDPA data are event driven due to it is CDMA network (Code Division Multiple Access). It means that you will see something during and after event. Like after download, but you have to have FieldTest open during download to record data. You are in HSDPA when after/during download in HDSPA CQI Status group CQI1-10 fields are more then 0.
Hope this helps, if you have more question just ask
I use both bluetooth and usb on the cingular network with my tytn.
And yes, bluetooth is much slower than usb regardless of the type of bluetooth on the pc.
I usually get 300-400 on bluetooth and 800-1300 on usb. higher speeds with vista vs xp (don't know why tho) I doubt you will ever get 1.5 mbs as you mention, unless you are the only person using that particular cell tower
@Pawlisko....My problem is that I do get 3G speeds when using the unit itself, browsing, streaming, etc..., but when I use it as a modem for my laptop, from the same location, during the same time frame, I only get one tenth the speeds. Are there different versions of the USBMDM.inf that would cause such a thing? I have experimented with init string settings, and for some reason, using NO init string gives me the fastest speeds.

eagle 1 - By your end of quote I can tell you that still you are thinking old way
Huge advantage of CDMA is it's multi connection to tower bases. There is no handover like in TDMA system. In large city your cell might be served by many towers (TyTN 1 to 6).
HSDPA is regarding of category 0.9/1.2/1.8/3.6 Mbps (current). During 2007 CeBit in Hanover 7.3 Mbps will be shown. It will go thru 10.2 to 14.4 Mbps (max) in near future. Of course like any other link you have to substract overhead of TCP/IP protocol data of avg. 20%.
Like fast ethenet - suppose to be 100 Mbps = 12.5 MBps, if you will get 80 Mbps = 10 MBps of real transfer you have very fast network.
If you have more questions - ask

drummer10630 - did you check your speed using any speed tester? Sometimes speed is relative. Remember that some pages are optimised for PDAs with less ads, better html coding etc.
First of all - do not change anything - no strings. Just put your APN in TyTN and dial *98# should be the fastest way.
Second - check if you have installed in your computer software like IM/update that will use some band without your knowledge. That can kill your connection for good.
And last - delete everything for comp - inf files, and related dlls. Install one more time and do not change anything. As plan as it can be.
As usualy - if you have more questions - ask
I can get about 70KB/s download with my laptop's built-in bluetooth module ( 2.0+edr) and tytn and about 150KB/s via usb ( i'm in Italy with VODAFONE operator ).
Using a 1.2 BT dongle on the pc will reduce speed at about 40KB/s ... this is the connection speed from the pc to the device and not from the device and the operator network ( network speed is independent from your pc to tytn connection ).
Just a question : how can be the tytn BT 2.0 without edr since the specs tell that only differences from 1.2 bt vers and 2.0 bt vers is only the speed increase and there isn't a 2.0 without edr in the bt specs ???

OK, let me answer.
I do not know how abubasim knows that TyTN does not have EDR but this is meaningless.
Your speeds are normal. First of all maximum speed is something which normally is never achived. Why? Because of interference, not optimal power scheme etc. Just like WiFi (IEEE 802.11g) you will never get transfer of 54 Mbps = 6.75 MBps even with protocols overhead (of 20%) = 5.4 MBps. Real transfer is 1.5-2.5 MBps.
Now BT speeds:
BT 1.2 - 721 kbps = 90.125 kBps = real transfer max 72.1 kBps so your speed of 40 kBps is normal with this type. I would said that this is good link speed.
BT 2.0 - 3 Mbps = 384 kBps = real transfer max 307.2 kBps but as per wikipedia data transfer is 3xBT 1.2 = 2.11 Mbps = 270.375 kBps = real transfer max 216.3 kBps so your transfer of 70 kBps is roughly 1/3 so it is about right. I would say that 110 kBps is what you may get, if more you are lucky.
I do not know if TyTN has EDR - in my opinion it may have, but it has to be chcecked.
Hope this helps, if you have any other questions - ask

You may have meant *99# ? ;-)
@Pawlisko :
i think the tytn has 2.0+EDR also if HTC website say 2.0 without edr ( this mean nothing if you read the BT specs ) .
I was using a samsung Z560 HSDPA before ( BT 1.2) and max download speed via BT in conjunction to my 2.0+edr laptop never reach up to 40KB/s.
Now with tytn i can reach up to 70KB/s and a stable 55KB/s , i mean tytn has real BT2.0+edr imho...

Right. My bad
Something that you may not have thought of. Set the baud rate on your Bluetooth serial ports to the highest rate at which you can communicate. Mine is set for 460Kbps. It made a serious difference for me. I didn't perform any measurements but I did see the difference. The default rate is 115200. This was the mistake that most folks made with standard modems. The default serial port rate was 9600 and a 56K modem needed to have data fed to it at at least 115200 to keep its compression engine busy. It didn't matter if you had a 56K data connection if you were only feeding it at 9600. The same principle seems to apply here, at least in my case.
Just my .02.

How do you set the modem to 460Kbps? The bluetooth modem is set as a standard modem at 115200, which is the MAX. I don't see an option for 460kps. Are you saying to set it up the BT connection as something other than a standard modem?
Hi,
I´m using my Touch HD as modem for my laptop.
Normally, this region I´m living in, offers HSDPA (O2) but when I´m doing a speed test, I only get a download rate about 350kbps, this is not even UMTS-speed. The acces point is right. Is the modem of my HD so bad? Whats the problem?
Thanks,

Hi Fl0w
I realise you said your ap settings is correct, however you may want to double check that / see whether there are alternative ap's that also work, but work better.
I'm on Orange and had the same problem - approx. 300kbps as a modem but no higher. Called Orange support, guy directed me to remove the Orange WAP ap (default setting when you buy the phone) so it defaults to Orange Internet. Presto, jumps to a consistent 1.2Mbit.
Why they don't configure the phone with the right ap in the first instance I don't know... perhaps its an attempt to minimise network usage.
Also, are you getting 300 kbit/s or 300 kbyte/s ?
If you are getting 300 kbyte/s then that is very good for HSDPA.

I'm guessing it's 300Kb/s and not 300KB/s since that's 2400Kb/s which sounds too crazy for HSDPA. Not to mention that bandwidth is always measured in Kb/s while data is measured KB/s (aka if its moving data it's Kb/s and if it's sitting in memory it's KB/s).
but if it is 300KB/s then.... DAM I wants that!

It must be the setting as I also get 1.2M from a good HSDPA signal.

After testing new firmware with two different routers at two different places I can definitely say it's got the same range and disconnect issues when compared to existent v.1 with fix applied. What is your experience folks?
Improved network speed over 5GHz band
Range is okay for me, but the speed that the update brings via 5 GHz band has improved significantly as compared to 12.1.A.0.266, a little better than PureXPERIence ROM.

Maybe is your router that is limiting the speed. I'm using ASUS RT-N66U, on 5 GHz band. 2.4 GHz band has always been limited to just 50 Mbps or so for both downstream and upstream (Xperia SP limitation).
My broadband speed on 5GHz band differs significantly at times too, from lows of 60 to highs of 120 Mbps. No idea why is there such high different though.
Sent from my C5303 using xda app-developers app
Speed is not an issue, I've got what I'm paying for when I'm close to the router.. It's range and disconnection I'm having problem with, especially when connected to an old G router. So I've applied the same trick i used before and it's working.
This I found at xperia Z forum and it might help someone else too.
1. Root your phone. Download and install Root Explorer or ES File Explorer (Explorer).
2. Make sure you manage how to use the Explorer as a tool to modify files in the /system folder.
3. Using the Explorer, browse to /system/etc/firmware/wlan/prima/WCNSS_qcom_cfg.ini
4. Make a backup if you wish. Most of the parameters inside need not be changed except the followings:
a. gTxPowerCap=30 (change to 60 increases the TX power)
b. gDot11Mode=auto (change to n to always connect as n, but if you sometimes want to use g, don't change this) (this I changed to auto though it was 0)
c. You may wish to play around with the other parameters as well
5. Now save the file.
6. Browse to /system/etc/hostapd/hostapd_default.conf
7. Again make a backup copy.
8. This is a long file. So please hang on. Amendment of the following is recommended:
a. max_num_sta=2007 (change to 10 to only display 10 wireless AP)
b. channel=6 (change to 0 can solve most wifi connection problems).
This might drain battery a bit faster, but I can live with that.
802.11g WiFi is normally weaker than 802.11n even on N 5GHz. Increase the TX will not only increases battery consumption, it also can get hot much quickly. I know this because I set my RT-N66U to 110mW from initial 80mW.
Why not just invest into a 802.11n router. Single band N300 is more than what you need since your broadband isn't all that fast in the first place. Just don't go for N150, it isn't built for the future when broadband hits 30 Mbps or higher and coverage is much weaker than N300 too.
Also, unless you're using custom ROM or on unlocked bootloader with advanced, there's no way you can modify these values. Both will void your warranty which can put your phone on risk.
Well, not everyone have N router, so you're not going to find it everywhere, and I like to be backward compatible. I was also thinking about decreasing Tx power, perhaps 60 is a bit too much. I'm on existenz v3 w/LB and root is enough to change these values. You're right about warranty, however think about doing this should know that.
hey, i have a new lg v20 ls997.
i unlock my device with octoplus box, i configure the apn for my carrier and got a calls,sms and data
my only problem is that i cant get any upload from mobile data, tried speed test and get 0 on the upload speed.
is there anything i cant do about it ?
i use it on GSM network (3G or 4G)
Thanks for help
Thank you, jeniav! Seconded!
I bet we're experiencing the same issue. (Not looking to steal the thread, just notifying you that you are not alone! And explaining the methods I have attempted, without success.)
TL;DR: Upload very very low, services which rely on upload (e.g. bank, eID, some web pages) do not load on mobile data, but do work properly when tethered (but only on the device tethered to the phone). Everything works as it should on WiFi.
Sincere gratitude for any assistance in this issue!
Details:
Device is LG V20 LS997, Software Version: LS997ZV7_04, Android 7.0 (Data worked fine on ZV5, updated due to stupidity.)
Unlocked with GCProKey. Changed from CDMA to GSM - WCDMA - LTE via HiddenMenuCall
For me upload over mobile data works IFF I tether the device to a computer, either via USB or WiFi-Hotspot, but never for apps on-board the device itself. Tethering Mode in HiddenMenuCall is set to Android.
HOW and WHY does it work properly when tethered? Does tethering work properly for you, OP?
The upload speed, tested with Speedtest.net by Ookla results in a measurement of 0.0-<0.5 kBps, download fairly stable around 35 Mbit, ping at ~20 ms to Copenhagen, 4G.
WiFi works perfectly (Up 111 Mbit, Down 220 Mbit, Ping 4 ms).
Tethered to a Win10-laptop: Up ~11 Mbit, Down ~35 Mbit, Ping ~16 ms. Results from the laptop, not the phone.
Attempts made/Google-fueled semi-random fumbling around done, with no change in outcome:
* New SIM issued by carrier
* Toggling of fast dormancy on or off with HiddenMenuCall
* Attempted to switch to Edge or HSPA with HiddenMenuCall
* GCF Flag set Enable with HiddenMenuCall
* Manually messing with APN settings
* TunnelBear VPN
* "Engineering mode" in HiddenMenuCall contains no information in any category. (E.g. It says "AMR CH: ", with nothing following "CH:")
* Tried RRP 5, 6, 99
* Setting "Network mode" to anything else besides "Automatic" yields a response of FAIL, whereas Automatic yields SUCCESS.
* AMR WB ON
Telenor/Vimla-network in Sweden. Manually configured APN in same way as on ZV5. Previous Galaxy Note 3 N9005 had no issues.
Left to try:
* OpenVPN?
* Crying in a corner while chugging ice cream and beer, not necessarily in that order.
Hey, thanks for your replay, its annoying problem but if you change the rom to us996 it will be fixed, probably it some setting on the stock rom
did you figured out a way to fix this issue?

Hi!
I hav the same issue with my V20 - same Model number. No upload mobile data. However, I can use WhatsApp for text but if I want to upload a picture on cellular data - nothing, instagram works not at all, email and web browsing works without issues.
So - some sockets and network connections are blocked in this phone - great.
Seems there is nothing we can do....

Device is LG V20 LS997, Software Version: LS997ZV7_04, Android 7.0 (Data worked fine on ZV5, updated due to stupidity.)
Unlocked with GCProKey. Changed from CDMA to GSM - WCDMA - LTE via HiddenMenuCall
For me upload over mobile data works IFF I tether the device to a computer, either via USB or WiFi-Hotspot, but never for apps on-board the device itself. Tethering Mode in HiddenMenuCall is set to Android.
HOW and WHY does it work properly when tethered? Does tethering work properly for you, OP?
The upload speed, tested with Speedtest.net by Ookla results in a measurement of 0.0-<0.5 kBps, download fairly stable around 35 Mbit, ping at ~20 ms to Copenhagen, 4G.
WiFi works perfectly (Up 111 Mbit, Down 220 Mbit, Ping 4 ms).
Tethered to a Win10-laptop: Up ~11 Mbit, Down ~35 Mbit, Ping ~16 ms. Results from the laptop, not the phone.
Attempts made/Google-fueled semi-random fumbling around done, with no change in outcome:
* New SIM issued by carrier
* Toggling of fast dormancy on or off with HiddenMenuCall
* Attempted to switch to Edge or HSPA with HiddenMenuCall
* GCF Flag set Enable with HiddenMenuCall
* Manually messing with APN settings
* TunnelBear VPN
* "Engineering mode" in HiddenMenuCall contains no information in any category. (E.g. It says "AMR CH: ", with nothing following "CH:")
* Tried RRP 5, 6, 99
* Setting "Network mode" to anything else besides "Automatic" yields a response of FAIL, whereas Automatic yields SUCCESS.
* AMR WB ON
Telenor/Vimla-network in Sweden. Manually configured APN in same way as on ZV5. Previous Galaxy Note 3 N9005 had no issues.
Left to try:
* OpenVPN?
* Crying in a corner while chugging ice cream and beer, not necessarily in that order.

As mentioned above - same here. I wonder if we will see an Oreo update and if that could potentially solve this.... Not willing to write off the V20 completely yet.
sigh....
Hi guys!
Sorry, missed out on checking this thread after a month or two. Have completely overbooked and out of spare time recently. I have not yet found a solution, rest assured that I would've posted it here... like the good little nerd I try to be.
Was recently informed that there might be a root solution out there for LS997 ZV7, have not tried it but it is where I will be looking in the near future.

Hope it helps! And PLEASE do get back in case you figure it out. <3
Absolutely!!
I am also determined to figure it out. I really like the V20.
Cheers!
u can go to dial then 5689#*997#) has only 4 modes: DeviceTest, ELT Test, SVC Menu, Field Test.
Goto
Field test - NAO test - NAOT - NAO Setting - Nao Carrier
And choose Sprint, if no data upload. Choose None
your problem will fix 100% upload back again with no problem

DUDE - YOU ARE BRILLIANT! The links helped!!
It now works with my phone and here is how:
Dial in phone app: 5689#*997#
In the menu select: Field Test
then "NAO-Test"
then "NAO"
then "NAO Setting"
if not enabled click first menu item to enable NAO Test toggle!
then NAO Carrier
choose SPR (for sprint) mine was on "NONE"
phone will restart and BAM! Data works via cellular now for EVERYTHING.
Wooohoooo - can't believe it. So cool.
Cheers!
:good::good::good:
Thanks, but already tried that with no luck on my end; connects to the Swedish operator for 2G, but Mobile Data stays disconnected.
Very happy to hear it helped, though, enjoy!

I have the same problem and tried everything, including this "simple" method from quote. Im living and working in Croatia, and my phone is also Sprint version "unlocked" but I use Croatian T-mobile.
Please, anybody, do you have some solution for this problem? Thanks in advance
Hi All,
The problem is that the hotspot (2.4 GHz, Device identification:default, security WPA2-Personal) is correctly seen by the laptops but there is no internet connection. I received the Mi 9T last week and it's a great phone except for the hotspot not working properly. I received it with the global version installed, I did all the usual updates up to MIUI V11.0.4 (QFJMIXM).
On the Macbook Pro (Retina 2015, Mojave 14.6) there is a very slow, barely usable, connection which is confirmed by the MCS index = 0, despite the strong signal (RSSI= -26 dBm). Under the WiFi information on the Mac, the country code is missing and the transmission channel is usually an unusaul value (3, 7 or 8 I noticed). For comparison, when using the hotspot function in another Android phone (Honor 8X with stock ROM) with the same SIM card , the MCS index is 7, the country code is correct, the transmission channel is 6 or 11, and the download/upload is around 20 Mbps.
When using a Dell laptop (Windows 10), the laptop connects to the MI 9T hotspot and has an IP but the pages are not even loaded. Funny enough, when both laptops are connected to the wifi created by the MI 9T, they can ping each other correctly.
The data rates on the Mi 9T over 4G are really fast (>40 Mbps). The Honor 8X works perfectly when connected to the MI 9T, with rates > 20Mbps.
Reading other discussions online, someone fixed it with
Code:
adb shell settings put global tether_dun_required 0
I checked the correct value after rebooting (zero as expected) but still no/slow internet on the laptops. Same with adding DUN in the APN type. I also tried to change the SIM from slot 1 to 2, no difference at all.
As a last desperate chance, I unlocked the boootloader and flashed the European version (QFJEUXM) with TWRP. The flash was perfect, but the problem is still there exactly as described above with the Global ROM.
Is anyone else having a similar problem? Do you think that other ROM (Pixel Experience, LineageOS, etc.) may fix this?
I'd really like to keep the phone because the hardware is amazing, but the overall experience is quite a pain with such a limitation on the hotspot function.
Hope someone can finally fix this
Used hotspot many times with notebooks, phones, consoles nad never had a problem. you could try to set cellular settings manually. I'm on 11.0.4 also Lineage worked ok
Yes thanks, I tried to use the same APN settings of the other android phone with the same SIM, still same problem.
Update: I have upgraded to the latest weekly ROM (MIUI 11.2 20.3.26), unfortunately the country code is still X3 when using the hotspot, both at 2.4 GHz and 5.0 GHz. The only difference is that at 2.4 GHz the MCS level is 0 (even if internet works normally) and with the 5 GHz setting the MCS is 7 or 8. In both cases internet works fine, but the country code is an issue with the firewall on other devices.
Any suggestion or help is greatly appreciated as I really need the hotspot function to work as per the other Android phone!
