Sony :: VGN-Z21 And Intel 5100 AGN Drops Under Windows 7


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.

Sony :: Vaio Z-540 Wireless (Intel 5100 AGN)
I've been using my Sony Vaio Z-540 without a problem for about a YEAR
until recently (about a month?), my wifi has been acting up.

My wireless card is Intel 5100 AGN

The problems are:
1. Sometimes, I do not get wireless from the startup . my wireless isn't even in the Device Manager...

2. When I do get wireless (Device manager confirmed), wifi connection disappears with even the SLIGHTEST MOVEMENT!

3. When I do lose the wireless driver (no more on the device manager), I put it to sleep, wait 5 seconds, wake up, and my vaio detects it. [but this isn't the case for ALL the time, sometimes I have to restart the vaio]

I thought it was a loose wire or loose card, so I opened it. The wireless card is bolted down with 2 screws. So i put everything back and it still has the SAME issue.

Also, I've updated the Intel 5100 Driver to the latest (When I finally got my Wireless driver seen on the device manager) but still the SAME problem, so I'm back on my OLD driver. still same problem, of course.

when I do have my wifi, my wifi just disappears with the SLIGHTEST MOVEMENT on my laptop. It has to be still...

Ethernet connect, however, works 100%

HP/Compaq :: HP 8530w Intel 5300 AGN Drops Out
I have the HP 8530w and a D-Link DIR-615 wireless router and am trying to make them work together. Using the G speed (54mbit), the network is stable (signal quality is excellent). But when I try the N speed, the situation is different. The network starts working as it should, but when loaded (big files transferred), the network suddenly dies and windows vista can take up to a couple of minutes before it discovers the missing link. During that time, the 5300 AGN still receives packets from the router (10 beacons per second as per setup in the router). But no packets are sent (checking with Intels statistics tool).

So it looks like the Intel 5300 AGN doesn't send any packets all of a sudden OR that the DIR-615 has become temporarily deaf. But disconnecting/reconnecting in vista make the network work right away indicating the problem is with the Intel 5300.

As an ekstra test, I tried having the Asus EeePC 1000H (also has 802.11n draft) transfer the same files while the HP 8530w was and then the network was MUCH more stable. The HP 8530w experienced 1 dropout but the EeePC continued transferring at full speed. Obviously the Intel 5300 AGN has severe problems talking with the DIR-615, problems so big it cannot figure out how to recover normally. :-(

Needless to say, I have tried playing with most settings in the Intel 5300AGN and also with the DIR-615, but without success. The network breaks down, always.

On the plus side, the EeePC 1000H is stable.

I wonder if it is possible to exchange the Intel 5300 in the 8530w with another wireless lan? I'd prefer to have a card that works.

Sony :: Intel WiFi Link 5100 AGN Driver
I recently installed Windows 7 Home Premium 64 Bit edition on my Vaio FW490 (upgraded from Vista 64). I received the free upgrade disks from Sony. When I checked my device manager I noticed that the driver version for the WiFi Link 5100 is 11.4.3.9 dated 5/28/09. On the Sony Site, they list the version for Windows 7 as 12.4.1.11 dated 10/8/2009, and when I checked on the Intel site, they are recommending driver version 13.0.0.107 dated 10/21/09.

HP/Compaq :: FPS In Games Always Drops Then Comes Back Up And Then Drops 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,.

HP/Compaq :: Is The Intel Wireless 5100 (AGN?) Card Removable Or
The DV5T seemed to be working pretty well for me and no real wireless issues.

What has happened is that since I upgraded to Windows 7 and the new drivers, I get some hitching, rubberbanding in games, slow speeds at times, etc.

Now I know Windows 7 is pretty rock solid and the new drivers came from the HP site.

But when I started googling, seems TONS of people have issues with the 5100 card and maybe I was just lucky before.

At first I noticed my card speed goes from ~50 MBPS to max of 130 MBPS. After reading, it seems even though my router supports 40ghz dual channel yadda yadda, the card only goes to 2.4 so it can't really run at 40ghz is my understanding and that 130 MBPS is pretty much the cap.

That said, it was that way before the Win 7 upgrade so that shouldn't change anything.

One thing I noticed is that in my device driver before the upgrade, it was a normal 5100 but now with the drivers, I see a 5100 AGN.

I can't find how the AGN and non-AGN versions differ?

Could it be I have AGN drivers for a non-AGN card?

Lastly, is this wireless card removable and upgradable or can I use the slot (empty) that I have for another card and disable the wireless 5100 through BIOS?

Dell :: Studio 1535 With Intel WiFi Link 5100
I'm getting myself an Intel WiFi Link 5100 to replace the current Dell 1510N card in my Studio 1535. Is the Intel WiFi Link 5100 fully supported by my laptop?

Are the number of wires same for both cards? Any specific steps that I need to do when replacing the card? This is my first time doing this so I'm a bit nervous.

Acer :: 1410 & Intel 5100 Wireless Weak Connection
I'm really trying to like my new Acer 1410. Everything was working great until I tried to connect thru the wifi. Turned out the connection was really weak. This is in my house where all my other laptops have had no problem connecting.

So I try for a couple of hours trying every setting possible on my router and on my laptop settings. Finally, I open up the bottom of my laptop and find out the black wire that goes to the Intel Wireless card isn't even connected! In fact the metal connector itself is missing entirely

So me not knowing much about electronics, I cut off a 2 inch wire (with connector) from my old laptop's wireless card and taped it to the new laptop's open black wire. Plug it in and now the signal is better, but it still sucks. Any advice anyone? I really would rather fix it myself if I can. Would it work better if I solder the two wires together? Or is the Intel 5100 a POS and nothing is going to help it?

Dell :: Slow Wireless Connection: Studio 1555, Intel 5100 Card
as of 2 hours ago my high speed has been stuck at 1 Mbps, much slower then its usual 65+ that I've had over the last 6 days since I got my laptop.

I'm thinking I may have received a faulty wireless card, since when I checked my wired desktop downstairs it's still at it's usual 100Mbps, and my sisters Inspiron 1420 has its normal high speed.

Now when I restart my wireless adapter (Intel 5100) the speed fluctuates between 4-38 Mbps for about a minute before dropping- and staying at 1 Mbps once again.

I checked if there are any computers stealing my wireless connection just in case, and as I thought no one is .....

Sony :: VAIO Z-Series Wireless Connection Drops
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.

Acer :: 5100 (xp) Windows Won't Boot
Acer 5100 (xp) stopped working a few months back! It says windows could not start because the following file is missing
WINDOWS2|SYSTEM32CONFIGSYSTEM.

Telephoned acer for recovery disks! Problems is a bought laptop through a friend of a friend. As I didn't register laptop and can't provide password, they won't sell me disks.

Tried alt f10 but nothing happens. Enabled d2d and recovery in boot up screen. Still no joy.

I have managed to download recovery dvd's (x2) from bit torrent (Acer Aspire 5100 Restore DVD's) . I then set the boot priority to boot dvd first.
The files are iso. I have burned the image using imgburn on 2 dvd's. The disk starts the loading RAMDISK image. Then as it flicks to the acer recovery it quickly jumps to please wait.....

I am now going to decompress the files using winrar, then burn the files. But not sure this will make any difference.

Acer :: Aspire 5100 Cannot Install Windows XP
my gf has aspire 5100 with vista in it, and it sucks so I decided to install xp to it. I reseached from google that does it support xp and does it work and found out that it does, you just need to make custom xp-install disc to get the HDD drivers so that xp-installation finds the HDD.

When I install xp, I get past the filecopying-part fine, then it reboots as usual and tries to start windows, but in the loading screen with xp-logo it gives me bluescreen.

0x0000007B is the error.

I've tried many installing over and over again, but with no luck. Its possible that my xp-cd is damaged in some way, but I just dont think so.

Any solution? Seems like everyone else has had no problems with installing xp to aspire 5100 vista.

I believe that istalling vista back works, but its not the right solution, since its piece of **** and slow as ****.

Dell :: Intel GM45 And Windows 7
I installed the 64bit version of windows 7 a few days ago and have had some graphics issues ever since.

The best I can describe it is that it makes my screen look like an over compressed JPG image, all blocky and broken up, until I refresh it in some way then its fine for a while.

I have the intel GM45 chipset. I started with the drivers Windows 7 found after (clean) install but switched back to the ones provided by Dell when the issue showed up. That didn't cure it though.

Dell :: Studio 1555Random Drops In FPS
Spent a few days playing with my new studio 1555, I am finding heavy drops in FPS whilst gaming. I have spent all today trying to find the cause.

As an example, if I am playing DOW2, I get approx 30fps, every 2mins or so it will drop to 15fps.

I am expecting it to be heat related but:
1. I cannot monitor the GPU temps
2. There is no program I can find that recognises the GPUs speed to check if it is down clocking
3. It only lasts about 2 secs then I shoot back up to 30fps.

I have tried vista 32 and vista 64.
I have monitored temps with HWMonitor and all but an ACPI are fine, the ACPI temp gets upto 93c as other users reported
I have tried turning off my wifi and playing offline in case it was network related
I have checked all drivers and updated where necessary
I am now at a loss.

Dell :: SXPS 1640 Random Performance Drops
I have a Studio XPS 1640 (3670 512mb, P8600, etc.) that I mostly use for gaming. During the past few months, I've noticed that occasionally when I'm playing a game, the FPS will suddenly go wayyy down. For example, I was once playing Oblivion and getting around 40 FPS, when all of a sudden the FPS randomly dropped to less than 10. The same thing has happened in other games such as TF2. I think that this may be due to overheating, because the computer still seems sort of sluggish even after I close the game. Anyone know what I should do? Maybe adjust the fan speed/get a cooling pad?

Sony :: VGN-C1Z (Intel 945PM) With More Than 2GB Of Memory
I just bought 2x2GB (DDR2 667MHz) of memory for my VGN-C1Z laptop (unfortunately I did not check before if 2X2GB was supported). Now, as far as I understood the Intel 945PM should support this, but the laptop in itself was said to be 2GB limited.

Using Windows XPPsp3 with those 2X2GB success to boot but at the end I got black screen (I see the Windows logo and progression bar, it stops displaying some sec before the startup sound), then I success to remotely connect to the laptop through VNC, here I can see that Windows is reporting 3GB which looks "normal", and under driver tab I can see in system area a warning under the line "Mobile Interl(R) 945GM/PM/GMS/940GML and Intel 945GT Express PCI Express Root Port - 27A1" saying "This device cannot find enough free ressource to work properly (Code 12). If you want to use it you need to unactivate one of the other system device" [message was in French, this is my translation], the version of the pilote is 7.1.0.1015. I'm using BIOS version R0035J4, in the BIOS only 3GB are reported. Running Everest I saw that PAE is supported and activated, and the memory is detected, you can see here the Everest report: [url]

If I boot with 1x2GB it's ok (so the mem slot works ok against 2GB). If I boot with 1x2GB + 1x512Mo, it's ok too, so It's above the 2GB limit announced.

I tried to change the video driver, and also switch to VGA with same black screen of course.

So... what can I do next to try to have 2x2GB working (even if only 3GB are available) ? Does it looks a driver/Windows issue ?
