Hello everybody,
I am using an XDA2 (=iMate) which sports a SDIO slot; furthermore, the device is listed in sandisk's compatibility listing. To connect to our wireless network (811.b), I use the Sandisk SDIO-Wireless-Lan-Adapter. I had no problems connecting to the access-point, I get a stable connection immediately, the indicated connection speed is 11 Mbit/sec. Since the distance to the ap is very small, link quality is near 100%.
The problem is that the maximum transfer performance I get is very poor. I get no more than 250Kbit/sec (=30Kbyte/sec), no matter if I do webbrowsing or simply copy files from other computer in the local area network. This is nothing compared to the ~5000Kbit/sec (=600Kbyte/sec) that an 811.b adapter should be capable of. I tried changing channels, but that did not change anything. I also hard-reseted my xda2 and installed nothing but the sandisk-drivers...no changes. Alternatively, I tried the driver from socket....works, but no changes in performance.
I have got the same problem at two different wireless networks (at work & at home), so it seems that the problem is on my system. I cannot test more than these two networks, since I do not know any others.
Has anybody got an idea what could cause this problem? How fast are your XDA2s with SDIO-Wifi?
Thanks in advance,
Stephen.
I had the same problem I returned my card and got a Socket one instead (from Expansys) I worked immediately.
After I returned it I read somewere that you must set your access piont to work at only the slower 11mbs and not the faster 22 or 56mbs and that will resolve the Sandisk problem.
I cannot verify this as I had returned my card, but my access piont was a Dlink one runnig at 56mbs

hi stephob12,
after reading this read i have googled around and found an article about socket sdio wlan card in a german computer magazine. the wrote that the sdio-specs do not allow transfer speeds > 35,7kb/sec regardless what sdio-card you are using (sandisk or socket). your performance of about 30kb/sec is really near the theoretical maximum limit.
i have no experience with those cards but i had planned to purchase one for my xda2 but i am slightly disappointet about that sdio limit :? . at home i use a bluetooth connection to my dsl access point and the speed is very good especially when you know that bluetooth with its 723kbit/sec is much slower than 802.11b with 11mb/sec.
i will now overthink whether to purchase a sdio wlan-card or not. at least not for the price of around 100 us$ or euros they have at the moment.
regards
peter
Hi,
can you post the URL of the article you found?
or send it per PM if you prefer ...
and what do you mean with "socked one", which one is it ?
and no one has any information about how the Compact Flash one is working, by using the back pack - this would be an alternative, don't you think???
ciao
the card is a "SOCKET" you can see it on www.expansys.com it is offered as an alternative to SANDISK at thew same price.
Thank you for the quick answer,
now I sow it, it seems to be more interesting than the Sandisk, I wanted to buy one ... but in that case it is worth to wait, to find a Socket near to where I live
May be I can find it in China or in the USA,
there is another brand - I forgot the name - which will be sold soon at CompUSA ...
I'm trying to find it ...
wil post it when I got it

Cheeper SanDisk SD WiFi card
Hi,
i think ive found (cheers google :wink: ) the same SanDisk wifi card u guys were talking about for $85 US (£47 GBP sounds much cheeper) at blueproton.zoovy.com so i was gunna ask if ne1 had ne experience with them but u obviously do.
just a couple of questions, am i right in guessing that SDIO stands for Secure Digital Input Output? how secure are these devices? what sorta encryption base do they use? and does ne1 know if there is any talk of bringing out a faster (22g or 54g) card on SD or CF?
Cheers
Smiley
Smiley,
SDIO WiFi card offers you WEP with 128bit key and this is your basic Wifi security. I am not sure if the SDIO card does any encyription. I suspect not.
As far as I know there is no 802.11g card (SDIO or CF) yet. I just read the news about a 802.11g chip for mobile devices. See below :
http://www.infosyncworld.com/news/n/4968.html
This may mean we may see cards based on this chip in the future or there may be products using this technology to deliver built-in Wifi capability.
Hope this helps. Regards

Hello all,
I've got this Socket SDIO WLAN card, and it's terrible with regardws to throughput, but it's okay besides from that. I can't even stream a 300kb/s video, and that's not impressive... In cradle via USB it's of course okay, and having problems with SIP VOIP client as well, very very sad.. I wrote Socket, and got a reply that indicates they're sorry for this, but that it's caused by some HW-related issues on my device (QTEK 2020)
Urgh...

Just bought an XDA2 - partly because I understand WiFi add-ons will be available soon.
Any news on this - or, if they are out there, anyone with experience.
My home wireless network is Apple Airport, by the way, but includes a PC without problem.
Thanks...
I didn't believe there were any plans at the moment for a dedicated Wi-Fi backpack. Instead take a look at the SDIO Wi-Fi card being offered by SanDisk:
http://www.sandisk.com/retail_sdwifi.html
My friend thought he had picked up somewhere that the XDA 2 had an internal slot that is eventually going to be used for wi-fi. Can anyone shed any light on this?
I certainly would prefer an integrated wi-fi solution so that I can use the sd slot for whatever I decide.

havent heard about a wifi backpack apart from speculations from people here
but i have heard about an upcomming sdio wifi card which also had connectors for sd ram cards at the same time
SD Wi Fi with256Mb of storage
Check this link out, This could be an answer to many problems.

"My friend thought he had picked up somewhere that the XDA 2 had an internal slot that is eventually going to be used for wi-fi. Can anyone shed any light on this?"
I think this is related to the marketing hype generated by O2 etc. Essentially they are referring to the capability of inserting a CF card based WiFi solution into the XDA2 backpack.
Finally…some competition to Sandisk / Socket SD WiFi
Do you want to connect to your WLAN ? No problem…
Mobile Planet is selling the PRETEC SD WLAN cards.
Installed one yesterday…works like a charm in my MDA II.
After playing / experimenting (but never being able to reliably use it)
with Sandisk and Socket cards I have now 100% reliable WiFi connection.
at what speed and i'm not talking about the reported connection speed but the real world speed
thinking if the sd interface can reach those 11Mb speeds when sending
Speed...oh well, I'dont have any tools to test it.
POCKET SKYPE works...

CF Wireless LAN card
This is just to report that I just bought and fitted a ProLink WL201 wireless LAN card and it works like a treat, including with the access point our local pub landlord has set up. I'm very pleased with it as I can now answer all the quiz questions that I don't know. As this CF card is about a third of the price of many others, I thought you'd like to know.

Are you using the backpack, or do you mean it's an SD card?
Thanks!

wtharp2, It's a CF card in the backpack - a little cumbersome but it saves a lot of money in UK as gprs is expensive with O2. Regards, Derek
Hi guys,
is possible that the shift wifi is power-less than others notebooks?
i explain, i've a 20mb connection at home and a wi-fi zyxel router, i connect to it my shift and also my asus g1s. when i download something from internet my asus download approximately from 1,5mb to 1,8 per second. and is a good thing. If i download the same thing from shift it don't go beyond 800kb. i've never seen a download like on asus.
This have sense? don't know why.. is not a big problem, but is courios.
have same here,
At home my con.speed is 1Mbit. Slow!
At work is normal 54...
I guess it's wireless router that is the problem. (Mine USR, has more problems...)
I get this too.
I can get 17m/bit on my PC which uses a wireless card, 8-10m/bit on my daughters HP laptop and 4-5m/bit on the Shift.
You have to remeber the specification of the device can also have a bearing on the results. My Core2duo 3.6ghz, with 2gb of highly overclocked RAM, RAID0 Raptors and IP35 Motherboard, will ultimately process download speed faster than the Shift would. Plug a P2 450mhz based machine with a 8gb hard drive and 128mb RAM into a wireless network, believe me, you won't get tremendously fast downloads!!!
Performance issue here too :
Using a Netgear WNR854T and I can see the Wi-Fi connection switching constantly from 54 Mbits/s to 11 Mbits/s. Getting really low data rates...
Yep, on the Shift I'm on about half to a third of what I get on my Presario (true d/l speed vs connection speed). In fact depending on 3G performance I can get better d/l speeds that way...
I find in general wireless strength to be sub par on the Shift. My HX4700 PPC has better range and speed than the Shift. Because I use the shift to mainly just surf pages it isn't an issue...but d/l'ing large files in emails is a pain.
While we're discussing wireless on the Shift, is getting it to work under SnapVue a priority in the project? I see that and the SD card as the 2 key issues (for me anyhow)...another donation coming to help with these elements and as thanks for work to date.
my wifi works fine, seems to work better than on some other devices i have

wifi isn't a priority because the driver doesn't even exist for WM6. will have to recompile CE5 one if that one is working at all.
so that'll be a big pita
also, wifi will only work if SD works.

Thanks- SD card working would be a big bonus indeed...I got about 7 meg left on Snap Vue...and with no calendar sync'd...
I guess the only reason why I mentioned WiFi (apart from my naivety about drivers etc) was the duopoly we exist in here in NEw Zealand means 3g/HSDPA data costs are horrific. Try $40 for 200meg (yes, meg) a month! Vodafone have been known to say that New Zealand is their most profitable country on the planet (read "most ripped off"). And if fact the news today talked about our commerce commision bashing them around for lying about their cheap rates to an audit group...it p!sses me off to no end, but what am I gonna do?
Anyway's look forward to further Shift developments.
I have to review my initial comments. Last night I had very fast speeds in spite of the less than stellar reception showing for the strength...so I suspect the wireless strength shows as being less but actual impact on speed might be minimal....
I'm trying to come up with a solution to add wifi to my vogue without loosing my storage, does anyone know of either a bluetooth wireless adapter that works with the Vogue or of an SD or MicroSD wifi card that also has storage? I've found an adapter for microSD to SD and already measured it and it should fit with the extended battery cover with the OEM battery.
Has anyone accomplished this? and how did you go about doing it?
You are basically screwed on wifi. You can probably set up a BT pan though at home.
There is a wifi micro SD card but very little testing has been done. The card would stick out of the slot probably 1/4" if not more.

I've seen that, but having something stick out isn't a viable solution, which is why I found a microSD to SD adapter that will fit between the stock battery and the extended battery cover, this does work using the spectec SDIO wifi card, however I then lose my storage card. I've been looking into the eye-fi card which doesn't support AD-HOC I'm debating about picking up the 2gb version and attempt to hack the firmware to get it working but I was hoping there was a bluetooth wifi adapter I know they exist for palm but I haven't found one that works with ppc.
If anyone would be willing to help with trying to get the eye-fi 2gb+wifi card working on ppc that would be great.

What are you talking about with the microSD to Sd adapter? You are basically screwed if you want wifi & have 2 options.
1. Dump Verizon & stich to AT&T
2. Get the Omnia or Touch Pro from Verizon.
Let me guess you don't have a data plan with Verizon

No, I have Sprint and I have an unlimited data plan however it would be nice to add wifi especially since I'm now living in an area that sprin't doesn't have service in so I'm roaming on the verizon network and the data is slow as all hell.
looks like that wifi card is your best choice, you might try accessing your storage card via internet? Or just carry it around with the card...
and if you carry around a camera(I doubt you do): http://www.bestbuy.com/site/olspage...st=n&iht=y&usc=All+Categories&ks=960<br ></a>

Not sure what you mean by the accessory slot? Are you referring to the mini USB? At any rate the answer is no.
I bought my a500 in Bangkok. I've heard lots of reports saying that this device doesn't support 3g and it was marked "32g wifi" when I bought it, so I naturally assume it doesn't support 3g connection. However, I find out that the sim card slot does exist besides the micro SD slot, it's just covered by the warranty label.
Does this mean that a500 actually supports 3g connection? If yes, anybody knows how to activate it? I didn't find any option in setting to turn data service on.
A500 with 3g will be the coolest device!
unfortunately according to what i read on the web this model does not support 3G nor does the USB host support a 3G modem;
there is a new model coming out though that does have 3G enabled.
It's pretty clear on the box, manual and specs - WiFi.
USB wimax modem?
Does it support usb Wimax modems?
AFAIK, it does not natively support USB modems.

Don't try to insert a sim card in the slot. Reviews have pointed out that the in the wifi only version the 3g sim slot has NO workings, it's just a big hole down which your sim will vanish, never to be seen again, in addition to this, it will rattle around behind the screen, possibly messing up the internals.
!!!!!!!RESIST THE URGE!!!!!!!
it's impossible that the A500 support 3G natively because the HARDWARE is not here... if you open the device you will see that the
- card reader is missing
- the pcie 3G card is missing
- the pcie slot is missing
- the microchips and resistor are missing
For all the 3G system.
A501 will be the 3G version
A500 is wifi only
32G = 32 GigaBytes and not somehow 3G/2G
zhengyu. where and when did you bought it ?
Mobile Expo or Commart ?
The W500 support 3G modem since it's a windows system.
and the N500 at pantip I really doesn't know what that model does maybe it's the name we give for the 16G version
555, su su.
you can use a phone and tether by wifi or buy a mifi-30 from iFox I think you can got one on 4th floor at pantip plaza
could you maybe explain how to open the device? i would like to have a look at the ssd and if i can replace it with a bigger one or with a hdd...

The internal storage isn't an SSD, it's flash modules soldered directly to the motherboard, so no user upgrade on the internal storage. Well, theoretically you could possibly upgrade the flash modules themselves, if you're really REALLY careful and have access to that kind of hardware
Thankfully, since you bought the Acer, you have a full-sized USB2.0 host port on the tablet itself, so you can plug in a nice multi-terabyte external HDD if you really need that much storage. May need to check out this link in the Dev section if you want to plug in an NTFS-formatted USB drive though.
Thanks !!
When I plugged in my cell phone, I see a /dev/ttyACM0 device show up. PPP seems to be also present on the system along with 'chat'. These are the pieces that enable a cell modem connection. So I think eventually someone will be able to tether to their phone or USB modem.
alright, according to varius posts, this "slot" propably is only a black hole
I will not try to insert a sim card any more
Pity on the pad, hope that Acer will have an upgrade plan
all the 3G talk should be close to solved this way.. read this post, and you can use huawei dongle's for 3G now.. it works fine here.. and is fast!
ZTE MF668a
I'm working with Thor rom v14.2 and 3g path.
Folowing the instructions for connecting the modem, finaly I get
- phone coverage in the icon of the task bar,
- I can acces APN's in settings, register my conection with the provider ...
- and the ligths of the modem are OK (blue indicating 3g coverage)
But when I run in terminal ppp-start.sh the messages are:
# su
# ppp-start.sh
inserting modules
insmod: can't open 'system/lib/modules/usb_wwan.ko'
insmod: init_module 'system/lib/modules/option.ko' failed (File exists)
starting pppd
but nothing happes with the connection
I've search for the modules and usb_wwan is not there but option.ko is in the correct place.
Is the modem the problem?
Have I to edit the 3g file?
I think the error is before of 3g file is launched.
Thanks a lot for all the good work eveybody is doing.
I confirm, A500 working like a charm with 3G USB dongle.
I use Taboonay ROM with huawei 3G stick and it's perfect !!!
