Internet Only Slow On Computer All Of A Sudden?

Aug 19, 2012

the internet today became insanely slow (I have wireless fyi) , something like 100 kb/s which used to be 2.0 mb/s. I can't even load a YouTube video at 360p. A few things have happened recently which may be the cause. First, I left my computer on all night, but since it has been off, so I don't think thats it. My mom recently turned off my computer by holding down the power button. I have searched my computer for viruses with 4 different programs and nothing has come up. I have also restarted my router and modem multiple times and nothing has happened. AND, I did a 3 hour long fragmentation of my hard drive/ cleaning of the computer.

Very Slow Internet On One Computer

Mar 7, 2013

I just installed a wifi card in the back of my computer. it only seems to recognize about half of the networks that my laptop recognizes (sometimes it doesn't seem to find my own wifi for a while), but shows everything with full green bars. connecting is difficult but can be done. it shows that my connection is healthy, but the internet is very very slow, it takes about a minute to load google. i am comparing the connection on my machine to the one on my laptop, and they seem pretty much identical (this is info i've gathered through ipconfig /all and also network connection details in windows 7). the only different information is that the IPv4 addresses are slightly different for each machine (which i think is correct). when i diagnose the connection it says that ''the device or resource (DNS server) is not responding"

i've tried flushing and renewing and releasing my IP in command, i've rebooted and reset the router about a billion times to no avail, i've got the latest drivers for the wifi card ('sabrent wireless-g 802.11g pci adapter / ralink turbo wireless lan card).. i tried changing my preferred/alternate DNS entries to google and the other one everyone recommends.. nothing is working. the internet is still exceptionally slow and the connection occasionally drops for a second or two.

New Computer Is Running Really Slow On Internet

Jan 15, 2012

I bought a sony vaio I3 2.1 ghz 4mb ram laptop yesterday, and it has a very unstable wireless internet connection. The internet might be super slow at first, then drop entirely to where it says "you are not connected to the internet," then after not changing anything it will have a normal connection speed for a few minutes before repeating this cycle again. I have a macbook pro that I've had for two years connected to my wireless internet, and it has never had a problem. Even now it runs as usual on the wireless internet. I also have two ps3s that are working fine on the wireless, so I know it's not the router or signal.

HP W1907v Slow Internet Connection On A Computer

Jun 28, 2012

I have a HP w1907v with a slow internet. [code] I go on Command Prompt and type in 'ping <my ip> -t' and my ping is quite low. However when I go to something like YouTube, my ping goes super high! It jumps up to 1000. Also when I go on any website at all, my ping goes super high. It happens mainly on websites which have flash on it. I have a Belkin F6D4050 Enhanced Wireless USB Adapter. I thought it was the USB but it wasn't, because when I put the USB into another computer, the internet was fine. The ping didn't skyrocket or anything. It was constantly low.

Wireless Internet Slow On Single Computer Only?

Aug 2, 2012

It should be known that this is not MY specific issue, it's a friend's issue... but I am posting it for him as I know nothing about networking. Don't worry though, anything you post here I will relay for him to do.Is this a wired or wireless connection issue?

Wireless

How to run and post an ipconfig /all output of the computer(s) in question for review.Here it is:

C:Windowssystem32>
C:Windowssystem32>ipconfig/all[code]....

So here's the deal, my friend has horrible down speed, usually less than 1MB/s according to Speedtest.net, sometimes it hits 2MB/s. However, his brother's in the house have at least 17MB/s, which I can assume is their actual speed that my friend should have... however, he specifically does not.He had a very old wireless card that was installed on his motherboard (desktop PC) that I assumed was the issue upon him first telling me, and from the issues I was personally able to see. For example, he'd constantly disconnect... his internet would just die for him specifically, and then come back. His brother's never lost internet when he did.

After that, I figured his very old wireless card that was installed was just kicking the bucket, so I instructed him to replace it. He went out and bought a new wireless USB adapter, and then uninstalled the network card.Even after all of this, his internet is still poor in terms of down speed. HOWEVER, rather than his internet dying for a few minutes at a time every so often, his internet "stays connected" if that makes sense? For example, we'll be on Skype in a conference call, and his internet will be loading pages very slowly, and Skype will constantly show that it's going from "green - online" to "gray circle - connecting". During this, he's still in Skype, but it's very poor quality from him speaking, and laggy as well.

Internet Slow / Not Working On One Computer - Low Bandwidth Range?

Jun 25, 2011

I have multiple laptops and a PC in my house all connected to Verizon's wireless/wired modem/router.My laptop's bandwidth ranges from 7-20 Mbps, while the desktop cannot seem to rise about 1 or 2. The wireless card for the desktop was a USB Wireless G adapter, in the process of trying to figure out the problem, i replaced it with a b/g/n PCI card. This did NOT resolve my problem. So in a fit of desperation, I reformatted the Desktop, and Restored the modem/router to factory defaults (in that order) neither worked.

Internet Slow When External Antenna Connected On Computer

Mar 22, 2011

I just realized that my internet is slow when my antenna is on top of my computer. I have a pci card with an external antenna connecting to it. If it's on top of my computer, my internet is slow, but if I move it three feet in front of it, it's fast. This makes me think that my computer is somehow blocking or conflicting with the signal. Is this normal, or is there something I can fix in my computer? Download speeds with the antenna on top are around 0.54Mbps, and if I put it as far away as I can, I get around 20Mbps.

Computer Causing Internet To Be Slow On Entire Network

May 4, 2012

I have 2 computers on a network, and 3 devices that use wifi on the same network. Basically when ever computer A is connected, every single computer or device on the network runs extremely slow, if at all. I get anywhere between 1200-2000 ping on pingtest with 2-60% packet loss. Even the speed on the "infected" computer A downloads extremely slow. I'm at a loss for this problem, everything runs slow and its because of the one computer connected to it. I have virus software on this computer, but its not the best so i'm not ruling out malware or viruses right off the bat.

Devices: Blackberry, Iphone, macbook (all wifi)
Computer A
Runs windows xp 32 bit,
amd processor
onboard video

[code].....

The internet modem runs to a router (Dlink dir615) then to a switch (or hub, if you will) and then to the 2 computers. The entire problem is solved by unplugging computer A from the system. But other than that I have no alternative.

Slow Internet On Main Computer But Normal Speed On Laptops

Jun 13, 2012

My Main computer (which has a wired connection to router) internet is running so slow, i mean so slow that i cannot even do a speed test, it keeps failing, im continuously getting server timed out messages when browsing, and to watch a youtube video of 1 minute long it will take about 5 - 10 minutes to stream it before i can watch it. However despite the above the two laptops and ipad work great, i have a braodband speed of around 16megs. Now here is everything i have done so far. After calling my ISP to se if it was their fault, which it turned out not to be, they got me to change all the DNS and IP settings to manual, they gave me all the numbers to put in. Again that did not work so i used namebench to find the quickest DNS servers for me, that didnt work ethier so i just reverted all settings back to automatic as they were before.

Can't Access Internet All Of A Sudden

Feb 6, 2011

All of a sudden one laptop can't access internet. I've tried everything I could find on Google. Can't access wirelessly (although computer IS connected to the router, no problem) OR even when I directly connect via ethernet. Other computers in household are having no problems whatsoever. Laptop in question (Dell Inspiron 11z, Windows 7) was working FINE until yesterday morning. Nothing I did (deliberately) to the computer (i.e. no downloads, new programs, etc.). Just stopped working. I'll see if I can list some of the stuff I've tried (in addition to the obvious rebooting, restore points, etc.): DNS flush winsock reset ipv4 reset ipv6 reset release and renew DNS.

Sudden Loss Of Internet Connection

May 12, 2012

While playing the online game League of legends i suddenly lost internet connection. when loading pages some will not connect and I'll get a message saying I'm not connected and should try reloading, refreshing the page usually fixes the problem, occasionally multiple refreshes are necessary. I've never had this problem before and it's rather inconvenient for me as I need internet access for university.

Something is turned off as far as I can tell. And I can't figure out how to turn it on.

All Of A Sudden PC Refused To Access Internet

Apr 23, 2011

My PC is connected via Ethernet cable to my Sky Broadband box, which also provides internet access to my laptop. Yesterday, all of a sudden, my PC refused to access the Internet. Whenever I try to go on any website through Mozilla, it says server cannot be found, for any site. My Network Status says it is fine, and my laptop still works perfectly, but my home PC all of a sudden just can't surf the Internet. Weirdly, a couple of my games can still work online, though and chat clients like IceChat are unable to, aswell as VOIP clients such as Raidcall. I have no idea what it is, since my Internet was fine the day before this hapened on my PC. I've been through the usual steps of checking your cable, restarting router, diagnosing connection etc, but it still fails to work.

One Computer's Download Speed On Network Is Slow?

Sep 1, 2012

When connected to my router on my main desktop, I get download speeds of about .3-.85 mbps, I have comcast and a linksys N router, as well as a N wireless adapter in my desktop. If I use my laptop, I get around 10 mbps download speed, (Speeds are as of [URL]) but they still remain at .3 mbps on my desktop. I have tried two different wireless adapters in my computer. One is the Linksys AE2500 Dual Band N adapter, and the other is an ASUS N13 N Adapter. I have gotten the latest drivers of both adapters, but speeds stayed very low. When I connected the computer via ethernet cable, it ran at 16mbps. So I think that something must be wrong with some wireless settings, since I've tried 2 different adapters and was getting the same result, unless both were faulty I suppose. I also don't think it's my router's issue, because the wireless is working great on other wireless devices. I am using windows 7 on the desktop.
