Wireless Modem speed

I have set up my XDA with the XDA-developers SE ROM v1.1, and setup the wireless modem exactly as per the O2 instructions - and it works - I can surf and collect e-mail on my laptop via the xda!
But it's quite slow, and WinXP reports the connection as 9.6kbps. It seems a bit faster than that, and I obviously do have a GPRS connection, but is there anything I can do to speed it up?
Many thanks in advance

Contact O2 as it should be a network issue. You must also bear in mind that many networks set priority for voice over data (for obvious reasons), and therefore you may find ridiculous speeds on GPRS during Peak Hour. Check out the speeds at night, for example, and try finding a bandwidth meter on the net. There's one that I used (I forget which one, exactly) and I've clocked my XDA at 39 kbps on one partcular occassion. However, all these vary from network to network and I find the average speeds available on my network (where GPRS is still in implementation stage) to be round about 18 - 20 kbps.

Hi,
The speed reported by XP is the interface speed. I use the Infrared port and it shows 9.6 as well.
This is not the GPRS Speed, but the IR speed.
regards,
Silver

I am seeing exactly the same results here in the US with T-Mobile. It is obviously much slower than using GPRS on the device itself. It appears as if either it is not bonding multiple channels, or somehow the IR/virtual com has restricted itself to 9600.

How to switch between wi-fi b and g ?

hi all,
according to o2 mini s has Integrated Wireless LAN (802.11b/g)
http://www.my-xda.com/xdaminis_spec.html
but i couldnt find a way to switch between b/g or is it possible manual switch?

anyone? :roll:

I think in some roms its disabled for example the T Mobile rom. Im not sure there is a way to switch it on or off on the Wizard. Either way just set your router to mixed if possible. You really wont see any difference between b or g on your wizard anyway. The only reason I would see for being able to connect to G is connecting to routers that are set to G only.

There is no setting on the device I can see. I don't believe its a 'g' device capable of 54 Mbits, I think this is just marketing. Its a 'b' device which can connect to b or g. Just like blueangel, alpine, universal.
Can anyone prove otherwise?

thanks guys I’ve asked that because i have connection blockage problem with my wireless router, it suddenly happens and while connection to router is alive and working I can't send or receive any data from internet or from other wireless connected pcs, only way to get it going is turn wifi off and on, i reckon its something to do with router then

My Qtek Wizard establishes connections up to 54 MBit/s, when disabling the power saving mode. Usually connection bandwidth is 18 MBit/s with standard settings.
So Wizard is definitely 802.11g capable!

So disabling the power save mode kicks G in then ?

I don't think it is a big deal G or B, wifi is nice, but the processor is so slow that can not deal with more data speed than b.
only personal opinion.
Happy New Year to every one on this forum

I think 802.11g is only available after a firmware upgrade. Seem to recall reading somewhere that the Qtek and I-Mate branded one have had this done and the T-Mobile and O2 ones haven't.
Next O2 rom update maybe.

Interesting. So you are setting power save mode to 'best performance' in order to disable?
Where are you seeing the connection speed, this is on your router?
I'm not doubting you but I'd like to see for myself. Thanks.

I just rechecked the g-issue more detailed.
Allthough changing power saving settings to "best performance" I couldn't achieve more than 18 MBit/s again. Maybe the display of 54 Mbit/ before were caused by some bug in my router.
The bandwidth is shown in the "WLAN monitor" menu of my WLAN router (AVM "Fritz!Box Fon WLAN 7050").
After switching to 802.11g-only mode my Wizard wouldn't reconnect or find the WLAN at all.
But 18 MBit/s is a speed step, that is used in 802.11a and g only. 802.11b+ doesn't have a speed step between 11 and 22 MBit/s. (see: http://en.wikipedia.org/wiki/802.11#802.11a)
So my Wizard 18 MBit/s must establish a (obviously not 100% standard-conforming) 802.11g connection.

i was just on the club imate site lookin at the k-jam specs and heres what is says:
-IEEE 802.11b/g/e*/i* compliant
-Internal WLAN antenna
-11, 5.5, 2, and 1 Mbps per channel, auto fallback for extended range
*Will be supported soon via free ROM update from clubimate.

wifi painfully slow...

I'm not sure if this is normal or not. I just got my Cingular 8125 and the wifi is very slow. I don't know how to measure the actual speed but for instance on my broadband connection, going to Google.com opens up in about a second. On dial up it takes about 5 seconds. However, on my phone using wifi, it takes about 20 seconds. When using wifi on my laptop, it is comparable to my broadband speeds my router is connected to.
I have pretty slow GPRS service as well and wifi is comparable.
I get the same slow speed on 802.11b as well as 802.11g networks (g network with registry hack)
Is this normal? The wifi speeds with the unit brand new out of the box was very slow. I flashed the rom and even overclocked to 240, the wifi internet is still painfully slow. I don't really find this useable. If I go to a page with images and such it can take a minute or so.
Anyone have any suggestions? Are others getting good speed on wifi. I tested by watching a streaming video and the speed shown on the bottom of windows media was 18k.
Were my expectations too high? Is there a setting I have incorrect?

Always best to be sure that you are actually using the wifi connection - Try disconnecting the gprs first before you connect to wifi. I have an issue where if I leave my gprs connection enabled all the time it takes precedence over my wifi no matter what.

Tried that but still no luck. When connected by wifi, I see the little wifi icon on the title bar. When connecting to GPRS, it shows the E and actually a pop-up saying it is connecting to GPRS. This part is actually working great. Uses wifi by default when wifi is on and GPRS is not.
I did try to disable GPRS entirely but still get the same slow results.
I also changed the wifi setting to maximize performance instead of save battery life. Didn't seem to matter.
I may experiment with Opera Mini or something to see if I can get some improved speeds.

no problems with wifi here. getting a faster connection than GPRS, even at hotspots.

I had a problem with my wifi connection in that the DHCP server giving out an incorrect address for one of the DNS servers. This made the wifi slow, because Internet Explorer kept on trying to lookup the IP of a host using the broken DNS, and then falling back to the second in the list.
You try specifying a DNS server manually to diagnose the problem.

Cingular 8125 WiFi Fix that works!
Believe it or not the support for this product from HTC, the mfgr, is great and fast! That being said, I like most users have spent days hunting for solutions to the problem and you will not find them anywhere. But here is the solution:
First you must have an unlimited account for data usage or forget your WiFi...well at least simply. Also, you must get Cingular to flip a switch for your 8125 to automatically switch from WiFi to GPRS and back depending on what is the best signal. It works great once the switch is set.
The only way I found to do this was to call support and make sure you get to the HTC support group. They will guide you quickly through getting setup but you must tell them about the switch so they call Cingular and have the switch set. For some reason Cingular, no surprise, does not seem to know about this when they sell you the plan and the phone.

Thank you so much. This sounds like the solution I'm looking for. So are you saying to call HTC support and they will contact Cingular to have the switch set on my behalf?? Or do I just call Cingular and tell them to "turn the switch on"?
I do have an unlimited GPRS for data usage.

what a crock of steaming brown stuff :x .... what exactly does wifi have to do with your telco? ... nothing. There maybe some registry entry that Cingular have set when the device ships which causes poor WiFi speeds but your GPRS data plan has nothing to do with WiFi data, unless you are talking about connecting to Cingular WiFi hotspots. The only changes needed will be on your device not within the Telco network.

before calling support, try this:
Go to comm mgr and turn off the phone. Then turn on WiFi and let it connect. Check your speed with www.2wire.com. If your speed is still slow, and another PC connected to that HotSpot isn't (test the PC with 2wire also) then your 8125 is bad.
Using the WiFi icon v.s. the "E" icon is no way to determine what wireless system you're using btw...

Ok, I tried 2wire. My laptop connected to my wifi network and clocks in at 3.2Mbps and my 8125 is showing 221 kbps. multiple tests showed 228, 205, 220). Perhaps it is unrealistic to expect similar speed as my laptop.
I turned the com manager phone back on and connected via GPRS and the speed test came back at 64.8 kbps.
So it does look like this method is working. I can live with 221 kbps.
By the way, I emailed Cingular and HTS. I got the following response from Cingular:
Thank you for contacting Data Support!
There is an additional setting that you need to enable/disable manually every time you switch between GPRS and Wi Fi, please take a look at it:

I think it's always going to be slow because of the way the phone is designed. Probably small bus interface. My friend has a 6700 wich cpu wise is pretty much the same based on comparison but his is much faster through wifi.

"I think it's always going to be slow because of the way the phone is designed. Probably small bus interface. My friend has a 6700 wich cpu wise is pretty much the same based on comparison but his is much faster through wifi."
No no no no no no and no.
small bus interface? for heavens sake... you have heard that there is something called a "bus" inside computers and that it is used to "transfer data" and this "bus interface" is small in the qtek so it is a viable candidate to blame slow transfers on.
no.
any memory bus designed after 1980 is capable of 200kbit transfers.
the main reason for the horrid speed of the 9100 is the stupid software design where every system call in a program gets interrupted by the os which in turn, after checking who-knows-what, in the name of "security" and "stability", and then executed. Of course this hinders performance dramaticaly without affecting stability and security a single bit: it still crashes. the difference is that it is also slow.

I'm running Xelencin's custom 2.17 ROM for T-mobile on my 8125. His ROM sets the device up to work with an 802.11 g wifi connection. I kid you not - I have measured 900 to 1200 Kbps on my wifi at home (comcast) and at work (T1). It's blazing fast.
To measure your speed, go to www.dslreports.com. Click on the lowfi version at the top of the page. Then click on speed test. Then choose either 600K or 1 MB and then let it do the test.
You may have some setting wrong.

I have an 'adhoc' wireless network (running at 11Mbs) and i stream large lossless (FLAC) audio files to my Squeezebox 3 wireless music player with no issues whatsoever.
However, the MDA can't cope at all. FLAC files play great from the MiniSD, but wifi performance is worse than terrible.
Yes, the wifi speed of the MDA is s**t.
That said, if anyone has any tips on how to increase perfomance please let me know!
Thanks.

My Wifi would not work at all when I updated my ROM but this utility fixed that and sped things up. I recommend backing up your device before executing because I have only tried this on QTEK 9100 with a beta 2.8 ROM.

Excuse me for my ignorance... But then how do you explain that the 6700 can handle 700kb wireless while 9100's usually around 220kB? The Intel proc on the 6700 seems comparable to the Omap,no?

What exactly does this cab change?

Reconfiguring DNS may make a significant improvement?
I came across your post after my own concerns with my I-mate K-Jam (Wizard) WiFi performance. My GPRS connection was at least twice as fast.
My problem was that is was taking at least 30~60 seconds to locate a web page and another 10~15 seconds to open the page. Once connected it seemed to work OK but operation via GPRS was still faster.
My K-Jam has a ROM that permits G connection and my AP is set to G only. After reading all the articles in this post (and others), I ran the 600K download at DLSreports.com. To my surprise, my download rate was actually + 500kbit/sec which lead me to believe I might have DNS issues.
I used vxUtil (http://www.cam.com/windowsce.html) to check my DNS settings. My primary DNS being picked up from my DSL modem was the DSL modems gateway address which works fine in my Toshiba laptop. My secondary DNS was my ISP's backup.
I reconfigured my DSL modems DHCP server so that the DNS servers being dished up to my K-Jam are my ISP's primary and secondary servers and I performed a soft reset.
The speed increase was substantial! Pages are located and opened within 5 seconds now making my WiFi connection useable.
This may be worth a try for others with similar issues?

Simultaneous UMTS Tethering and UMTS Calling... possible?

Has anybody been able to get this to work?
If so, was it a Bluetooth or USB tether?

I haven't done it tethered yet (even though I use USB tethering), but I have been on a call with a bluetooth headset while surfing the web through UMTS/HSDPA without any issues.

There's definitely no problem using simultaneous UMTS voice/data connections on the device, I've been unable to secure either a Bluetooth-tethered or USB-tethered data connection on the desktop and a phone call on the device simultaneously...
If I try to make the call, it breaks the tethered data connection.
Maybe there's a way around this?

I can tell you from experience (or rather, experiment) that it does work. I tethered my desktop to my TyTN (cingular) to see if Counter-Strike would actually work on it (I tried all my previous phones to no avail) and I was surprised to find out that it worked! I had a ping of 100ms on average and the game was totally playable, no skipping or spikes. I then made a phone call to a friend to see if it would hold the connection and it did. However my ping jumped to 150ms and there was some mild skipping, but still playable.
BTW I am in Chicago, IL if that makes a difference to you. I know 3G speeds seam to vary from place to place.

Internet Connection

Hey, im new here , so hi.
I have a XDA Orbit with o2 in the UK.
I wondered if there was anyway of increasing my internet connection download, as i got a hack for a USB drive to use your sim with unlimited internet connection, and it works, but im only getting 0.03 mgbs, and wondered if anyone had any tips on increasing your download.
cheers

236.8 kbit/s is the max for edge
nothing any software can change
and thats theoretically and with max quality signal
as in what you will never get

i need your usb hack software.....please
i need your usb hack software to try out here in Nigeria. we have cases of flaws in telecoms internet platforms, and i think i can get a working unlimited internet connection down here..who knws, i might be able to tunnel you to my connection using OPENVPN..theoritically giving you a stable but guaranteed speed.
am not sure it will increase speeds though, as UMTS/3G gives about 300Kbits/s
but you never can tell..waht might come up...
