Sony :: Wwan Auto Drops After Few Mins
May 29, 2010
I downloaded and installed the GlobeTrotter Connect in order to use 3g/HSPA on my z11wn.
I could make may lap connect to internet via the inserted sim. However, the connection only last for few mins, then drops. The only way to make it works again is turn off wwan, turn on and restart GlobeTrotter Connect, sometimes I need to restart lap aswel.
this is very annoyed, because I can use mobile internet for only few mins, then must shut down and reset the WWAN adapter.

I have a M1730 with 8700gt sli GPU's. My problem is that, if i turn on the notebook and start playing a newish game,
it will run great for 20 mins or so, then its performance will drop dramatically, to the point of not being able to play due to framerate drop.
My instincts tell me that it is a heat problem, beacuse if i turn it off and leave it for a bit, i can turn it back on and play fine again.

Has anyone had issues with their DV5 with a Nvidia 9600mGT ? and FPS issues? I am playing DoDS, and for the last while (since I had my DV5 repaired by HP) My FPS in games always drops then comes back up and then drops again. I have installed many drivers with a clean driver install. (Used driver sweeper) I have even went as far as completing a whole system recovery again, to still run into these issues. It has become so bad, It ruins all gaming for me. Also, I think i have notice big CPU spikes, which might be causing issues... the specs are in my sig,.

I have managed to finally resolve my problems with my Windows 7 installation by redoing the upgrade, everything now seems great and all the original drivers/software (FN buttons etc) are working great. So far, Windows 7 looks great!
One problem I'm noticing and I've also found links on Google of other users complaining about the same is that the Intel 5100 AGN wireless seems to drop quite often. This never happened under Vista.
I use IRC quite a lot, and it's so frustrating with my Internet constantly dropping. Other laptops connected to the same AP (NETGEAR WNR2000) do not encounter this. The drops are extremely brief.

Have D420 here and was thinking if it's possible to use WWAN slot for any other mini pci-e cards like SSD or video decoder. Now Dell docs state not to mix WLAn and WWAN cards between their assigned slots.

I own a Z series Z540. After multiple Vista reinstalls and driver reinstalls, the wireless connection always drops. It would maintain connection for about 5 minutes, then it drops again. The wireless light stays on though.
I tried going on XP and ssee how that works out. Same problem, except that it drops when I MOVE it. And when it drops, the wireless light turns off, and when I move it back into a certain position again, the wireless light goes back on, and the wireless is back.
However, when I am on vista, the connection just drops for no reason, even without touching it, every 5 minutes. The light does stay on, though.

I have a new Sony F Series with an 820QM CPU. I notice the performance drops to a very low level when the unit is not on AC power.
I have chosen the high performance power profile, and set the Min and Max processor states to 100% both when on AC power and on battery, this didn't help at all .....

I have a Vaio TZ330E, it does not have any integrated WWAN. However I happen to come across a work provided plan that pays for wireless connect through AT&T 3G's plan. Can install the Integrated 3G WWAN myself? There is a place to put the SIM Card behind the battery... If so where can I purchase this?
Or Should I just get a PC Express Card or an AT&T USB Connect Card?
Anyone know whether a PC Express Card is better than the USB Connect?

im considering buying a Vaio Z from the US.
But since I live in Denmark (europe) and would very much like to use the build-in broadboard, i have my doubts that this will work?
Do the build-in card also support the european WWAN network, can it be unlocked from sprint or can the card be replaced?

I have a TXN29N and am in south africa, my ? is this, the vaio has wwan functionality linked to Sprint Mobile, obviosly I cannot use the sprint mobile service in south africa, can I use the wwan functionality here at all (on our mobile networks)? if so, how? on top of that the TXN29N has no simcard slot so how is wwan supposed to work (how do you connect to the mobile network without a sim)?
If you need to use an external modem (huwaei or such like) with a simcard in (like my previous laptop) then I don't understand why sony included wwan?

I have a UK VGN-Z3. It comes with a built in WWAN card, which allows HSDPA connection over T-mobile. My understanding is that the driver is a Quallcom Gobi.
I've clean installed Windows 7. After much hard work and searching high and low, I think I have everything sorted. FN keys work, sleep is available etc (I do have a sporadic wireless drop-off that I didn't have before but that's all). I've updated all the essential bits as per the extremely helpful guidance on here and elsewhere from BIOS through to smart network etc.
On the VAIO download page specific to the Z3 there are no Windows 7 drivers for WWAN. So, I downloaded the original ones from the "originally installed section. The Quallcom gobi didn't want to install at first but I found a workaround online involving changing a particular file [url]. So that was installed and I then installed the original 3G manager. Fingers crossed and, surprise, surprise, it didn't work. The 3G manager comes up with an error message basically telling me that the WWAN is not detected or words to the effect. I tried going to a more recent Z series (Z51) and downloading the equivalent drivers from there. Still nothing. There is some sort of further advice in the link above that might help me but :-/ I don't understand it...!
I use my 3G connection a lot as I'm often on the road and am totally lost without it...

I am going to get slayed on here and told I am an idiot but I have been trying all day to get my WWAN working on my VGN-Z31WN (UK) to no avail.
I got my windows 7 upgrade dvd the other day and installed it as recommended by sony i.e upgrade. After the laptop seemed a lot slower, my wireless connection to ages to come online and my WWAN (on a vodafone sim) had stopped working which is my main connection method as I travel a lot.
I was generally unimpressed, so after doing a little research (on here) i decided that a clean install was the way to go. I followed sigma957 instruction to the letter.
Everything was much quicker apart from the goddamn WWAN which still wont work!
I have been scouiring the internet all day trying to find a solution but cannot come up with a solution. Does anyone have the same laptop with windows 7 with a working WWAN connection? If so how have you done it? What software are you using for the connection manager? Which driver have you used for the WWAN? I have even tried ring Sony support but they aren't even open on frickin weekend!

We have a a sony TT290 that has what appears to be the gobi WWAN module in it. On the unit is only talks about Verizon. as an option.
However from what I understand the gobi works with AT&T as well. Looking that the unit there appears to be a place behind the battery for a sim slot, but it is covered by a plastic spacer.
So two questions, is there an actual sim slot behind the spacer and if there is has anyone been able to use it with AT&T?

I tried another software and it wouldnt connect.

I've been searching around but am having a hard time finding the answer to this one. Does anyone have built-in Sprint WWAN working on their Z (mine is a Z540) in Windows 7 64bit?
I can toggle Wireless WAN on and then see 4 Data Interface items listed in Device Manager that need drivers....

Ive just installed Windows 7 RC1 on my lovely Vaio TT VGN-TT11VN/X
Everything looks good, wifi quickly working but one thing i found doesnt work is the 3g smartcard internet access
Ive tried installing all the drivers, it recognises the Globetrotter Smartcard reader installed but then says cant install drivers when trying to install the software
Im running Windows 7 RC1 x64 bit version to take advantage of the 4GB ram
Anyone had any luck getting WWAN running?

I have done a clean install of Windows 7 64-bit informed by Firestone and others on this Forum. Everything works well - in fact arguably better in terms of functionality of Stamina/Speed switch - with one exception.
I have not been able to install the WWAN successfully. I have tried a number of times to uninstall and reinstall the drivers from links on this site and also even tried the Sony EU support site Windows 7 drivers with no luck. I have tried asking windows to search for the best driver with no luck. Globetrotter Connect has installed correctly, as far as I can see, but just doesn't pick up the WWAN card.

last month I upgrade the HSDPA board to the Vaio VGN-Z790LDX in order to use any sim card from any international cellphone company and it worked at first attempt .
now I just replaced the IFX-517 and the wwan to the Vaio VGN-TT290NBX and I have installed one IFX-517 having the sim card slot and I placed the unlocked wwan GTM382.
anyone did the same upgrade?
which driver are the best in order to make it working properly?
I am asking this because I did try to install the Option driver /Globe Trotter Connect and the Vaio Smart Network but for many times it was not succefully done .
the first times the minicard was in the device manager list but just till the laptop was on.......and after restart it was not there .
now finally after many times removing the driver and the minicard the system is working but I don't know for how long........
now I am wondering that I did mistake at the beginning because I mixed sony driver and Option drive and software.............in few words I made a Cocktail,

I will soon receive new vaio Z from Japan. As some of you know WWAN modem in Japan is locked to NNT Docomo. Japanese model has sim card slot but it's currently impossible to unlock Gobi 2000 card. In Europe vaio Z comes with same card unlocked.
On ebay you can buy unlocked Gobi 2000 puled from HP,Lenova or Acer. I wonder if those card will work in Sony laptops. Where can I buy unlocked Gobi 2000 that will work with sony laptops?
Also if somebody is interested here is the link with some photos showing how to replace WWAN card in new Z:

is there something wrong with the f21 bios? my dv5t shuts down after 20 minutes of use after I flashed it in. To top it off, the only reason i installed it was because a hp csr guy said it would increase battery life!
How do i revert back?

after a long ordeal that included, crashes and vertical lines, faulty nvidia card, technician coming home, heat sink being stucked, endless chats with Dell representatives, laptop going to the depot, getting motherboard and heat sink replaced, etc... I just got my laptop back yesterday.
After experiencing certain familiar symptons (again!), I decided to run Rthdribl... After just 2 mins, the GPU temp (measured with CPUID Hardware Monitor) rose to 95C very fast! I got scared and stopped it there (so who knows if it could get even higher).
I guess this is not normal, and that I may have gotten another faulty video card, right?
