Tecra S3 and A2 both with Intel 2200 BG - Poor instable WiFi access

My department is using dozen's of Toshiba notebooks (15+ years).
Latest generations up till the Tecra's S2, all went well using WiFi.
Problems started with the A2. Then the same happened with the S3. Both from day ONE.
Tosbiba NL suggested driver update: no improvement.
Test: 1 Single user - 1 Cisco 1200 AP (802.11b)- No or brief connection (2 minutes) possible.
Most of the time, the AP is not visible at all.
Tried different channels. No difference.
All other Toshiba notebooks with other WiFi adapter models, work well.
Test with a 3Com (802.11b) AP went better, but still a very poor connection/speed.
Test with a Cisco 1230 (802.11g) went better, but still
very poor connection/speed.
Intel suggestions re 2200BG:
Power Save Polling to be the cause. But offer no solution.
Bluetooth co-existance. BT is not installed the A2. BT is not activated on the S3. We don't see the relation here.
There is no influence from other other equipment, operating in the 2.4 GHz range.
Who does experience the same and is there any explanation/solution known?
Regards and thank you,
Bill

Hi Bill
Thanks for your post about your wireless issues observations.
I have read some postings about the strange wireless LAN issues and mostly the WLan driver update procedure have solved the problems.
As far as I know on the Intel website you can find the newest version of WLan BG driver.
I suggest to download it and to reinstall the driver.

  • I have an iMac and a MacBook with Intel Core 2 Duo processors. I realize that this is within the stated requirements for Lion.  However was wondering if by migrating to Lion this will result in too much demand on processor resources, thus a slower machine

    I have an iMac and a MacBook with Intel Core 2 Duo processors. I realize that this is within the stated requirements for Lion.  However was wondering if by migrating to Lion this will result in too much demand on processor resources, thus a slower machine than using Snow Leopard?

    Which iMac?  Which Macbook?   Both have had several model
    itertations, even within the framework of a Core2Duo processor.
    With that said, I have an early 2009 iMac 24", with 2.66 GHz
    Core2Duo with 8 gig of RAM, and in my opinion, seems to be running
    smoother and faster with Lion.

  • Lion 10.7.2 On both mac book pro and iMac, both with Lion 10.7.2, obtain repeated iCal event notifications from calendar or address book.  Cannot turn these off.  They repeat several times per session and every time computer is used.  How to diagnose this

    Lion 10.7.2 On both mac book pro and iMac, both with Lion 10.7.2, obtain repeated iCal event notifications from calendar or address book.  Cannot turn these off.  They repeat several times per session and every time computer is used.  How to diagnose this?

    First, uninstall "SuperTV" (whatever that is) according to the developer's instructions. It isn't working and it's filling the log with noise.
    If you have more than one user account, these instructions must be carried out as an administrator.
    Launch the Console application.
    Step 1
    Make sure the title of the Console window is All Messages. If it isn't, select All Messages from the SYSTEM LOG QUERIES menu on the left.
    Enter "BOOT_TIME" (without the quotes) in the search box. Note the timestamps of those log messages, which refer to the times when the system was booted. Now clear the search box and scroll back in the log to the last boot time when you had the problem. Post the messages logged before the boot, while the system was unresponsive or was failing to shut down. Please include the BOOT_TIME message at the end of the log extract.
    Post the log text, please, not a screenshot. If there are runs of repeated messages, post only one example of each. Don’t post many repetitions of the same message. When posting a log extract, be selective. In most cases, a few dozen lines are more than enough.
    PLEASE DO NOT INDISCRIMINATELY DUMP THOUSANDS OF LINES FROM THE LOG INTO A MESSAGE. If you do that, I will not respond.
    Important: Some private information, such as your name, may appear in the log. Edit it out by search-and-replace in a text editor before posting.
    Step 2
    Still in Console, look under System Diagnostic Reports for crash or panic logs, and post the most recent one, if any. In the interest of privacy, I suggest you edit out the “Anonymous UUID,” a long string of letters, numbers, and dashes in the header of the report, if present (it may not be.) Please don’t post shutdownStall, spin, or hang logs — they're very long and not helpful.

    Have brand new iphone 4s. Wifi signal is very weak even when very close to router. I have also an iPod Touch and when both are side by side, the iPod wifi signal is excellent and the iPhone wifi signal is very poor??!!! Hardware issue? or software issue? I was hoping it is just a software issue, but...
    Saw may web sites discussing this same issue; many discussions point to hardware problems but there is no official word from Apple about it, which is disapointing !??  Few discussions point to software problem with solutions based on try and error, and they don't seem to work.

    did not help at all; the problem continues the same

  • I have an iPhone and sync it with iTunes.  Just got my wife an iPhone also.  Is it possible to have 2 accounts in iTunes 1 for my wife and 1 for myself?  I don't want to mess up things like contacts on either phone.

    The best is to create another Windows user profile(additional User Account) where each one of you can manage your own account, library, playlist Apps, Contacts etc,

  • Dual networks, express and extreme problem with Intel iMac accessing both

    I have two airport networks setup to two different ISP's. One is setup using two Airport Expresses with a printer hung off one. The other is setup with an Airport Extreme with two USB disks.
    I have a G4 iBook 14" laptop and a MacPro 17" Intel laptop that see and can bee switched between both networks utilizing Internet Connect. They are running OS X 10.4.11.
    The other system is an Intel iMac 20" (late 2006) running OS X 10.5.1. The only wireless network it sees is the Airport Extreme. This is frustrating because I want to be able to switch to the Express network to print and cannot get the iMac to recognize the network. Before upgrading to 10.5.1, I could, on occasion, see the other network, now I can not.
    Has anyone experienced this and is there a way to fix it? I believe it is operating in 802.11n, but have no way to verify this.

    I miss posted this in windows. I reposted this in the Airport Extreme.

  • I have a mac Book Pro and and iMac, both with Thunderbolt. I connect my thunderbolt cable to each and each tells me that it is connected to the other, but when I try secondary screen in Aperture it is still grey and not available, what do I have to do to?

    I have a Mac Pro and an Imac, both with thunderbolt. When I connect the two together with a thunderbolt cable each recognises the other as shown in the system report, but when I try to use second screen in Aperture, the option is still grey and unavailable. What do i have to do to activate second screen in Aperture via thunderbolt?

    In actual fact this seems a bigger problem than I thought. Linking the two computers via the Thundernolt cable and selecting cmd F2 no longer shares the screen at all and Apple say it may not be able too in Mointain Lion - What are they playing at, hundreds of customers link computers together and share the screens - Lets hope they are wrong and tell us what we need to do other than move back to Windows.

  • Virtual PC v7.0.2 and macbook pro with intel cpu

    Is Microsoft Virtual PC v7.0.2 compatibble with intel cpu's?
    thanks

    Virtual PC for Mac will only work for the older PowerPC Macs.
    For the newer Intel Macs look at either Boot Camp from Apple <http://www.apple.com/bootcamp> or Parallels <http://www.parallels.com>. The performance of Windows with either of these solutions far outweighs Virtual PC.
    Hope this helps! bill

  • IBM Calgary IOMMU and ACPI NUMA With Intel Core i7

    I been recompiling my kernel a lot to include support for my RevoDrive 3 and I've come across these two options which I'm not sure whether I should leave them enabled or disable them. In the help box for both of these options it says that it's recommended to keep them on if you have a Core i7, which I do. Yet, in dmesg it says that it can't detect calgary or any NUMA modes. Is this something that should really be enabled or is it ok to disable it? They don't show up with the stock kernel and I haven't had any problems with disabling them.

  • Changes to appearance of repeat swatch and gradient (both with transparency applied) when .ai saved in PDF 1.3 compatibility

    I need to send a complex vector print to a commercial printer who requires my .ai file to be saved as 1.3 PDF compatibility.  All the graphics display & print correctly bar two elements:
    1. A gradient with transparency applied
    2. A repeat pattern swatch with transparency applied
    Both of these elements are layered between a solid colour background and a complex array of vector art.
    The gradient displays as solid white when converted to 1.3 PDF.  The pattern swatch displays partly white, with some elements of the pattern repeat visible as a watermark.
    1. I have tried to rasterise these elements within the a@rt, and while they both display correctly while in .ai format, as soon as I convert to PDF the appearance changes as above.
    2. I have tried to apply the transparency to the paint buckets on the gradient slider instead of applying it to the shape with gradient fil
    3. I've fiddled with the Transparency Flattening presets, Document Raster Effect Settings, and everything I can think of in the 'Save as PDF' dialogue box
    4. I've tried to rasterise the full file with an even worse outcome (all colour information lost, appears only on grey scale with fewer elements visible)
    Could this have something to do with spot colours or overprint?  Any help would be most appeciated!
    I'm using:
    Illustrator CC 18.1.1 (doc colour set to CMYK)
    on a Macbook Pro OSX Yosemite Version 10.10.1
    Apple Preview Version 8.0 (859)

    Hi Mike,
    Thanks for taking an interest! I tried rebuilding my gradient as suggested to see whether it would make a difference, but was still having issues.  Tried to save every which way with the save as PDF options in 1.3 profile.  Finally went back into the file to unpack each layer and see what I could adjust to save the appearance.
    Found this fix in my swatches palette: for some reason the swatches I was working with had converted to "Book Colour", something I never use.  I changed the dropdown back to CMYK and changed the colours from spot to process, which fixed the file    Relief after hours of searching and late nights!
    Thanks again!

  • I am using firefox 4 and my website looks different in the LCD and Laptop(both with same screen resolutions). The same looks ok with firefox 3.6. Why i am getting this difference?

    I am using firefox 4 and i can see difference in the laptop and the lcd. The site looks fine with firefox 3.6 for both and also for all the browsers. Only for firefox 4, things are getting screwed in laptop, as it looks fine for the LCD.
    You can see this link as an example.
    http://www.automationanywhere.com/products/automation-software-enterprise.htm.
    Even the footer doesnt shows the css in laptop, but the same is fine for LCD.
    NOTE: I have tested this on most laptops.

    Well I see that you and I share the same problem, I posted the same type of question and am anxiosly awaiting replies on this topic, as it is very important
    I own a small business, and every hour a customer cannot view my site is a customer lost to incompatibility issues.
    I hope someone can help answer these issues.

  • My 'zip code' says 'invalid' i'm from the uk and tried both with and without the space. any ideas?

    I want to register my printer but the lack of 'zip code' won't allow me to progress. A 'zip code' is a 'postcode' right? **bleep**? can someone help? I'm not a total spaz, this site is just pissing with me....... I hope. Thanks

    If the register page will not take the information then I would give HP Tech Support a call. The agent will be able to quickly setup the account and register the printer to you. It will be a rather quick process.
    In this case, it would be the most time efficient option.

  • How to get pages docs created on a macpro to show up on iPad and iPhone both with ios5

    Yesterday (October 19, 2011) I updated to the latest OS's and pages app on my macpro and ipad2 and iphone3gs. When I create a pages doc on the macpro and save it I do not see it appear on the ipad2 and iphone3gs at all including within the pages docs window. Yet my iCalendar updates beautifully across all three devices. My question is what are the steps to get a pages doc created on a macpro to "automatically" become available and thereon update automatically in pages on my ipad and iphone?

    on Mac OS X there is no icloud enabled apps at this time. iWork09 for Mac wont sync your data to iCloud.
    To get documents to the cloud and thus to your IOS5 devices you need to visit www.icloud.com/iwork and manually upload your files  ( or use drag and drop from Mac Desktop to the browser ).
    This is no joke. Spreaded all over this support forums you find people that wondered how to do it until it was found out that iwork syncing is only enabled on iOS but not on OSX.

    How to fix them?

    Try the Hard Reset
    After charging till full charge, at least 2 hours (preferably 4 hours)
    Toggle the Hold switch, make sure you dont see the red mark when you do the  next step
    Reset the iPod -> Press Menu and Center button simultaneously for about 10 secs till the Apple Logo comes ON
    Then release the buttons
