Signal So Poor / When Place The Laptop Right Next To The Router It Receives Excellent Strength?

Jul 11, 2010

I have a Linksys WRT54G2 router right outside of my room and i only catch 2 bars of signal strength. all the other laptops in my household catch excellent signal strength and their range is way farther than where my laptop is from my router.However when i place the laptop right next to the router it receives excellent strength, but as i move away it starts to lose signal. Sometimes it would disconnect at a random time also. my laptop is a dell studio 1555 running on windows 7 and my wireless card is a Dell Wireless 1397 802. 11g Half Mini Card.I'm thinking its the wireless card but i purchased a dell mini running on xp with the same exact wireless card and had no problem with the signal strength.

Lost Info On Internet Speed Connectivity And Signal Strength

Feb 27, 2011

On the right hand side of the taskbar I have the icons for battery life, volume, internet connection, etc. When I used to put the mouse over the internet connection it would show me who I was connected too (SSID) , signal quality, and speed.I began having some issues so I had to remove my Netgear connection and then reconnect.Ever since I did this all that shows up now when I put the mouse over it is now only says: Netgear and Internet access.How do I get the information back. It shows up on my desktop, but not my laptop.

Best Way To Troubleshoot Poor Wifi On Windows 7?

Jun 22, 2012

I'm having an ongoing wireless problem with my Windows 7 PC in that speeds are a lot slower than expected and I even get intermittent 'connected to network but no internet access' problems.I have two computers on my network: a Windows PC, and a Macbook. With the laptop my download speed is regularly 17mbps. But my PC can barely pass 7mbps. I ran speedtest with the laptop on the floor next to the PC so I know they both have the same line of sight to the router. My laptop also never drops the connection.This tells me that the router cannot be at fault and that it's setup correctly.I have the latest drivers for my PCI wireless adapter. Windows is up to date.Is it possible that the wireless adapter just isn't very good? (I bought it as it had good user reviews). Although it barely managers a signal strength higher than 2 bars (which according to Xirrus Wi-Fi Inspector is about -85dbm Very poor!).Is it likely that some adapters work better with some makes of router? I have a Netgear router and the adapter it TP-Link.

Can A Netgear Wireless Usb Adapter Signal Read Off Of A Linksys Router Signal

Feb 9, 2012

I just bought a Netgear WNA3100 wireless usb adapter for my HP Win 7 64 bit laptop. I have been trying for 2 and half days to figure out why my speed is slow, why i don't have a good signal, and/ or if I do have a bit of a signal to my luck, why my signal comes and goes. I don't have internet at home at the moment because I am trying to save up to go to school. I am picking up a public business signal from a block away (which I have asked for permission to use), but I only am receiving not much of a signal with the Netgear usb wireless adapter.

Poor SSD Performance On Windows 7?

Oct 22, 2010

After having rather high hopes for SSD Performance...I'm disappointed.I'm glad I got a test unit, because if I would've shelled out the cabbage for this, I'd be a little PO'd.I have an 8300 Quad Core 2.5 Intel with 4GB of RAM running Windows 7 Pro 64 Bit.Instead of trying to clone the old drive, I did what I thought was right and did a fresh install.I loaded up MSE, Office 2010 and all Windows Updates.Did a couple of tweaks (made sure defrag was off, DMA mode on instead of PIO, disabled indexing)I have all the latest chipset, mobo, video, etc., drivers.Yes, it boots into Windows to the desktop faster. No doubt.Yes, it opens up windows faster and programs SOMETIMES as well.But it multitasks terrible. If I'm download, installing, etc., anything...and try to move program to program, it's slow. To the point I think it's freezing up.I've read a few of the tweaks here...and I'm missing something I think.It's an Imation 2.5" M series 64GB drive. I know it's not the Vertex 2...but it has pretty decent specs behind it. Not the best, but it should do everything my SATA platter drive does better...period.It doesn't.What should I be looking for? (It shipped with the latest firmware, and trim is turned on...not like that matters since I only installed Win7Pro fresh a few hours ago...)

Poor Performance On Good Hardware -- Why?

Jul 31, 2009

I have Windows 7 (x64) build 7264 installed and encrypted on a 32GB SSD.

(I also have a 1TB drive for storage.)

I installed it about a week ago and lately it has been becoming sluggish and unresponsive at times. Mostly when loading webpages with lots of pictures or videos. I've tried 3 different browsers with the same result. When watching streaming video, it freezes randomly for a few seconds at a time when playing (but the video play bar shows that it's loaded way past the point where it freezes). I don't think it's my internet connection, because it's pretty fast (university) and I don't have these problems in ubuntu. Also, iTunes sometimes takes 5-10 seconds to gain window focus when I click on it.

I'm having trouble pinpointing where the problem lies. It's obviously not the memory. The processor does't seem to be under a heavy load (and it has 4 cores). Could it be the SSD somehow? It is one of the cheaper ones. My ubuntu installation is on the regular hd and works fine.

Poor Video Quality In Windows 7

Jan 2, 2010

I have been having this very annoying problem for over 2 months now. I'm running windows 7 ultimate 64-bit and Most video on my pc looks very pixelated. I was able to get vlc to work correctly again with an update to the latest version and wmp seems to work fine too. I'm still having very low quailty video in my slingplayer, skype video and certain flash videos on the internet. I have been searching google for any possible solution like using an older video card driver, a vista driver, and adding codec's but nothing seems to work. I'm not really sure if it's an Nvidia,windows, or a flash problem.

my specs
intel core 2 quad q6600
4gb ddr2 ram
soundblaster xi-fi extreme gamer
2 nvidia 8800gts cards in sli

my pc has 2 monitors plugged into it and i'm using ultramon I also have my cpu oc'd to 3ghz, so i put it back to stock speeds and still have the poor video qaulity so that wasn't it.

Poor Video Playback And Slow Boot?

Jun 25, 2012

My Toshiba Satellite L750 laptop has been having trouble playing Flash video, and Windows takes an extremely long time to boot. Flash videos appear to drop every other frame at best, and the sound in every Flash element is extremely loud and distorted. When Windows boots, it appears to finish booting in a reasonable amount of time, but the antivirus software and some minor background processes do not load along with Windows. They do not load until two minutes after Windows appeared to finish booting. During this two-minute period, there is no CPU or hard drive activity. These two problems have occurred since Toshiba reinstalled Windows during their many attempts to repair this computer. This is the same computer that I started this topic about. What did they do to this computer?

Proof Is In For Cause Of Poor Ivy Bridge Overclocking Temperature

May 13, 2012

After a ton of speculation, a bit of denial, and a ton of testing we finally have our answer. The thermal interface material change made by Intel when it went from Sandy Bridge to Ivy Bridge is indeed the cause of the excessive temperatures weve observed while overclocking. The first accusation was made in late-April by Overclockers.com, however proving it wasn't easy. The Japanese division of PC Watch somehow managed to remove the integrated heat spreader from a Core i7 3770k, along with the stock binding and grease. They then proceed to replace it with aftermarket alternatives, and the results speak for themselves.

Random Generated Urls Attacking Poor Pc

Mar 9, 2011

started when i downloaded some shady looking software off of a shady website got some bsod n my comp was randomly bsod-ing, norton keeps on popping up messages saying they blocked recent attempts to get into my system coming from what are obviously random generated urls (i went to one n norton got all at me) , but these are coming through my web browser, so i deleted all my browser files xept my important bookmarks n stuff and reinstalled Google chrome, but while reinstalling Firefox comp bsod'd halfway through so im not gonna install that google chrome wouldn't load up but i found some hack-ish thing to get it to load although i dont trust these login stuff on this website tried some i forget what its called command prompt input to fix corrupted files n tht may have stifled the bsod problem a bit, BUT i did a freaking full system scan with malwarebytes anti malware (cuz i dont trust norton cuz norton says this virus is trying to attack norton) and it found NOTHING.AND I HAVE HOMEWORK, well i guess i can do hw in safe mode, basically this is a problem tht comes n goes.

Poor Sound Quality (Asus U36jc)?

Jun 24, 2012

It sounds like everything is coming through a tube or from the other room. Especially bad on music with lyrics. The tune jumps out and the vocals sound like they're almost missing. With movies it's a bit better.I'm on a Asus U36JC, windows 7, 64*, with Realtek HD- which is where I'm guessing the problem lies...I've opened the Realtek HD Audio Manager and I notice that there are "sounds effects" that, when selected, makes the issue worse (seemingly in the same direction as the original issue) with effects like: "bathroom" and "cave". Yes I've turned that option to "none" and yes I've tried to adjust the EQ as well. No good.I've noticed that in my programs list, I've got 2 realtek programs running: "Realtek High Definition Audio Driver", and "Realtek Ethernet Controller Driver For Windows 7".

Extremely Poor Wireless Mouse Performance In-Game?

Aug 2, 2011

I have a Microsoft Wireless Mouse 4000 that I frequently carry around. I would like to try using it to play games, but it has serious issues. Outside of a game, the mouse works perfectly fine. In game, the mouse jerks around and stutters, making it utterly impossible to use. It does not occur with any wired USB mouses.

Having Poor Performance On ExFAT Formatted External USB HardDisk

Sep 18, 2012

Recently I have formatted my Usb External Harddisk with exFAT, as I heard of the benefits of it over FAT32. Its an IMATION Drive with 320gb storage. Device Properties: TOSHIBA MK3252GSX USB Device, The problem is that it takes forever to copy files from the drive as compared to when the format was FAT32. Currently, Im trying to backup all my files on my PC and I've been trying to copy out 60gb of Data that I started 10+ hours ago. The wierd thing is the progress bar moves a fraction and then stops for about 5mins before continuing the another fraction.

Poor SSD Performance: Cannot Enable RAID For One Pair Of Drives And AHCI Separately

Oct 23, 2012

I recently upgraded to an SSD. I moved windows 7 over to the new SSD and re-aligned the partition properly The drive setup is as follows:

2x 500GB WD Black drives in RAID 0
1x 120GB ADATA S510 SSD

In BIOS, RAID mode is enabled. You cannot enable RAID for one pair of drives and AHCI separately. I was assuming disks that are not part of the logical RAID volumes would be set to AHCI automatically. I have enabled NCQ in AMD RaidExpert for the SSD.WEI is 5.9 for the primary disk. The primary disk is the SSD.Other strange behanivour is that the RAID array and the SSD both appear as SCSI devices in device manager, and Windows won't accept the ahci drivers from ECS.

TV Not Picking Up Signal

I'm not ruling out that I've been unlucky enough to buy a dodgy VGA cable but I don't have another to test it with here.
