Sandisk wireless problems resolved - Networking

I purchased a Sandisk SD card and my connection with my network was ON/OFF ( mostly off!!) I got fed up and returned it to Expansys.
I noticed last week they offered an alternative from Socket - This worked immediately with no problems.
I have since read that that the problem with the Sandisk card is if you have a wireless network that runs faster 11mbs (and mine was 54mbs) you should turn down its speed to 11mbs and this seems to resolve the problems. This titbit is unconfirmed by me but passed on as it may help someone out there

XDA2 and Sandisk WIFI-SDIO Card - Very poor Performance?

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.

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...

PRETEC SD WLAN

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...
Speed...oh well, I'dont have any tools to test it.

I have to comment on Mobile Planet... It took me a year to get off their spam list after ordering from them once. Never again.
@vegasmda: you should replace the link in your posting by a more anonymous link (just for security reason). the current link leads directly to your basket Stanley...
i do not know what misuse could be done by this i feel that it's better when nobody directly lands in you basket.

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

T Mobile Bugs and Micro SD.

Hello! I plan to buy HTC HD2 - think it is the best phone right now.
But have couple of questions:
1. Does it have old bugs - sms bug, calls bug. Heard that it always uses gprs instead of wifi?
2. What kind of micro sd card does it have? What class is it?
Thank you

1. I have the USA HD2, and the bugs are nearly non-existent on my phone.
Yes, it's laggy at times, but I haven't ran into any trouble. When my wifi is turned on, my phone automatically uses Wi-Fi instead of t-mobile data service.
2. It comes with 16gb class 2 MicroSD card and can be expanded to 32GB.
Thank you!
the sms bug that was present on the hd2 is not around for the majority of people but i have read people saying their texts go to the wrong people.
the only real problem is that if you get more than 200 texts in your phone (in and out) it will freeze up sense entirely and you have to soft reset.
for now all we can do is keep our inbox managed and it works great

How To Run a 100% working Dell Venue Pro?

Please turn to the post on page 3 labeled as "VIP - Very Important Post". I have requested a replacement device for the phone below and have achieved positive results. Turn to the post on page 3 for full details.
I am putting a poll together to gather information on helping everyone, including myself, to achieve the best results with their Dell Venue Pro. Since we have spent our hard earned income on this phone, it would be great for all of us to have a great experience with it in hopes that Dell can promptly provide us with the proper firmware update to fix current issues. So please provide any information you have available that we can use to help your situation and ours.
(As of 5/03/2011)
Dell Venue Pro - 8GB Stock
Updates: February > Nodo
Firmware rev # 2250.1500.7004.105
Hardware rev # 112.576.2.0
Manufacture Date: 1/23/2011
Current Issues & Fixes:
1) Gmail manual sync issue - Solved - emails synced properly based on 30 & 1 hour intervals but not when done manually. Solved by deleting account and adding it again as a new account.
2) Lockup/freeze while charging - Not Solved
3) Lockup/freeze using Internet Explorer, Marketplace, Apps, Maps & Newsroom while using Wi-Fi - Not Solved - Should I request a replacement or wait for the Dell firmware update?
4) Slider Reboot - Not Solved - This is now a major concern, it seems as if the phone completely crashes upon opening or closing the phone via the slider.
4) Death grip - Not Solved - Yes, my phone does suffer the issue where holding it in the most comfortable way affects the quality of the signal
5) Low music volume - Not Solved
Comments:
I'd say that my phone works at 70% considering that my phone crashes often in the day especially when using Wi-Fi. There are moments that I can use Wi-Fi normally yet there are mostly moments that it crashes. I love what the OS and phone have to offer together, but the continuous crashing makes it unbearable after a while.
The answer for me was to replace the MicroSD with a Class2 card. For whatever reason the DVP doesn't seem to handle faster cards well; the higher the class of card, the more frequent the issues.
Since replacing my card I have had minimal issues; the phone works great on a daily basis for me.
Took me ages to get a Class 2 card (kept receiving a class 4 card in the post) but will hopefully get the card in the post this weekend..
I only have crashes when I use WIFI, and it tends to happen with big files (such as computer games or HD youtube videos), so long as I dont use wifi the phone works 100% of the time...
With wifi on, the phone will lock up 100% of the time.....haha

It's great to hear that your DVP is working great. I would love to take the chance of replacing the MicroSD card, but I'm not sure I want to void the warranty as of yet. So I'm trying to find solutions while maintaining the 1 year warranty. I've also heard of some DVP users having conflicts with their replaced MicroSD cards after they updated to NoDo. So that's another reason why I haven't made the switch as well.

Haha! I know exactly how you feel. The phone works great without Wi-Fi but with it on, I feel like throwing the phone out the window because of the constant lockups. Let us know how things work out when you use the Class 2 card while Wi-Fi is on =D

That is a chance, yes. But at this point, I'd rather have a working phone than wait for a fix that may or may not be coming.

Have a link to that? I have not seen anything about that yet.
EDIT: By the way, the thread title is quite misleading. Wouldn't something like "Poll: How stable is your DVP" be a better one?
I'd be surprised if anyone has a truly 100% working device, DVP or otherwise.
Just in case not everyone has seen it, there was a different poll on DVP stability a few months back:

That is my concern, that I am not fully convinced that someone is running a 100% working Dell Venue Pro. That is why it would be great for people to post information on how they were specifically able to achieve these results. So far only raremage has mentioned that replacing the MicroSD card works better with minimal issues. So it seems that there are individuals who voted on 100% and have yet to specify on how they have been able to have a Dell Venue Pro running flawlessly.

Another ordered Class 2 card and another class 4 card delivered...
Tried amazon, eBay, memoryzoo and mymemory.com and they all have class 2 cards, class 2 pictures but I have received 4 class 4 cards in the post...
NOt quite sure where else I can go to buy one from...so unfortunately no update on how it works with a 32gb card...

I purchased from Amazon on Apr 12 and got a class 2. the seller was BlueProton.
Thanks for the tip....The main page 1 star reviews look a bit dodgy to me, but will look into Blue Proton and see if he is certified.
Its the same link that folks here and also ZDNet had luck with.
Sent from my Venue Pro using XDA Windows Phone 7 App
It works
I have had a UK Venue Pro for the last two weeks and to date had no real problems. Logging onto WiFi does however only seem successful where 802.11n is available. We have 3 different Belkin Routers which are all n certified, it will not conect to a Belkin PreN one though. All are WPA. Hope that's of some hope to others.

read your post about WiFi and decided to play around here at home with router settings. I live in a fringe area, so WiFi for internet is a must. I work in town and 3g is good so there are never any connection worries. I only see the small amount of lag I do see, at home. My wifi band was set to b. I changed it to mixed. The speed change was immediate. Have seen no lag issues all day. I doubt this is the cause of others WiFi issues. However, it resolved the slight problem I had at home.
Well I have had the chance to really put my phone to the test during the holiday weekend and have come up to this conclusion. It is possible to have the Dell Venue Pro running at 99.9% stability. I have been running the DVP for the past 4 days without a single freeze or lockup. I have surfed the web, browsed the marketplace, downloaded software, used maps, sent emails, and everything else you could possibly do with the phone.
current Dell Venue Pro configuration
MicroSD: Stock 8GB
Wi-Fi: off
Bluetooth: off
Cellular Data Connection: on
Cellular 3G connection: off
Network Selection: T-Mobile
I must keep Wi-Fi off at all times. I have yet to purchase a bluetooth headset so I am unsure if bluetooth causes any instabilities with the phone. Also, since the 3G signal around my area tends to be inconsistent, I mainly keep the phone on EDGE network. Besides the extremely slow internet browsing, it seems that this is the only way for me to achieve the best performance & stability without voiding the warranty. So this is one temporary option that I would recommend to everyone who would like to have a phone that actually works. It seems that a major issue is caused by using Wi-Fi. So until Dell's upcoming update finally resolves this issue for all of us, we may have to use the DVP as a phone rather than a smartphone.

Lately, feeling much less pleased with the stability. Newly downloaded apps seem the most troublesome. Downloaded ESPN, Poynt, Weatherbug, TED and Flixter yesterday. Except for ESPN, each one caused a freeze either in the app or just after trying to go back to the start screen. ESPN didn't freeze, but wouldn't connect the first few times, and crashed out to the app list once. Today, I was able to run the first three without issue, and was able to connect to ESPN. It seems like once I get through the initial app settling period, things work a little better.
IMDB still behaving badly. It doesn't cause freezes, but Search just doesn't work. I don't think I can blame the phone... just a poor app!
Strongly considering the Sandisk Class 4 32GB Micro SDHC card upgrade now...

Purchased directly from Dell on February 20th.
Have 5.56 GB available
The reason I posted 100% is because every crash I've experienced has been by a poorly designed app. I just simply remove the app. Everything else works great, WiFi, Exchange Server synchs, etc. with no lock ups/crashes.

D'loaded big games (PES 2011, Earthworm Jim) etc, with no crashes....had 10 different apps and games d'loading at the same time with no crashing whatsoever...
Touch wood it stays this way, cos honestly it is a beauty this phone now...
I just ordered a Sandisk 32GB Class 2... through BlueProton! Hoping I get the card I want
I will try to come back here and let you know how it goes.
Question - how many of you got the Venue Pro with a completely black sticker over the SDHC card rather than the "warranty void" sticker?

[Q] Sandisk 16GB Micro SD Class 2, Future Shop on sale for $44.99

Okay... I know there are cheaper deals in the USA but for the cost and return policy I will buy this locally. This unit is going on sale starting May 6.
http://www.futureshop.ca/en-CA/prod...spx?path=53f07f2a1ed3dfd176e60862966939fden02
Question is though, is the Sandisk 16GB Micro SD Class 2 card a working card for this phone ? There are so many postings but hard to pin point if this is a good working card with no reboots or data loss.
Appreciate quick responses as I want to pick this up before they sell out.
Thanks !
generally after the samsung focus nodo update the phone is not showing the symtoms of earlier sd card problems. Sandisk should be fine, class 2 or 4 seems to be the best class right now for this phone; even though microsoft orignally said class 4 or higher. You should check out the sd card thread sticky
Card has been purchased... I've done 3 finger salute and connected to laptop. Seems there was an update from Microsoft, so let that run and update.
Now syncing the card to all my wonderful music. I've loaded 4GB so far. Another 12GB to go. Will report sometime tomorrow if any reboots or data loss occurs.
Oh my... I guess I had more music and pictures than I thought ! Anyway the total storage is 22GB and available memory is sitting at 1016MB. Essentially I have maxed out the storage. So far no lag, no blips, no reboots, and no data loss. It's only been about 90 minutes though ! Will leave it over night and then use it more. Play music, read emails, make phone calls and then see what happens.
Any othe suggestions for testing this out?
Seems to be working perfectly. If anyone has suggestions to testing the load and trying to get the card to foul up please make suggestions. Future Shop has a good return policy but it needs to be returned with in 14 days of purchase. So far though the card works !
Can you check the speed (using WP Bench)? If it's good, I think I'll buy one of these.
So, bought the card - only the one that showed up was a class 4 16gb San Disk (as opposed to class 2 as listed in the order). So far has been performing fine, although I have had the occasional slowdown / lock-up (which may be a function of the phone trying to find music on the card). WP Bench score for storage access has ranged between 2.8 and 5.6...
