Internet Doesn't Work All Of The Sudden?

Nov 5, 2012

It's a 64 bit machine, with windows 7. He fills out surveys and gets money from them, and I don't like to work on his machine because of this. But... He called, so I came over and Anyhow... I'm worried that the Ethernet has gone bad on the motherboard, but they bought a USB stick for wireless internet, and that didn't work either.I realize I have basically no worth while informationHis router works fine, if you plug in another computer it can connect to the internet, but his computer can't. Something is turned off as far as I can tell. And I can't figure out how to turn it on.

Linksys Wireless Router :: Wrt160n - All Of Sudden Access To R2 Ceases To Work

Nov 10, 2011

I am cascading a wrt160n (R1) and a wrt160nl (R2) which are hooked up LAN port to LAN port (via a DLink power line adapter).  R1 is hooked up via dhcp to the internet.  The whole system works wonderfully for several hours until all of a sudden wireless access to R2 ceases to work (though I still can access everything wired).  [code]

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.

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.

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.

D-Link DIR-615 :: No Connection All Of A Sudden?

Jun 26, 2011

I've had my DIR-615 since December 2009, and have never had an issue to date. I've used my XBOX, Nintendo DS, iPod touch, and my laptop with it with no issues. Well, yesterday, my mom decided to switch ISP's from Qwest DSL to Xfinity and I thought that if I plugged it right in, it would work since the setting's hadn't changed. Well, that didn't work. I can access the internet with the modem plugged straight to the computer but I still need to be able to access wireless to keep the home free of war, So thinking that I needed to look at the settings by going to 192.168.1.0, I tried. And tried, and tried again. And it says the same thing every time: that the page is not available. In the past, I've done it to change the settings for my DS but sometimes it took me to the Qwest page for it

Sudden Decrease In Download Speed

Jan 25, 2012

About a week ago i started experiencing very slow download speeds... things like streaming online videos and having to wait which i have not had to do for the last 4 years. I did a speed test on multiple sites and my download speed comes out at about .2mbps and my upload is still where it should be at .6-.8mbps. I have a 12mbps connection so this does not make sense at all. Originally thinking it was malware, I formatted both my hard drives and did a clean install of windows 7 and it did nothing to resolve the issue. Could it be that my wireless card's radio is failing?

Router Blocking Connection All Of A Sudden

Apr 4, 2011

I suddenly could not go on my web-site anymore(this situation happend a lot already),I went to the server to see whether Apache was running and serving the web-site,tested it locally and it worked,then i checked if my external IP changed, it remained the same.And I know, if i reboot the router 1 or 2 times it will get back to normal, but probably stop working later again. I enabled inbound logging on my router and all of a sudden it shows me this picture of a blocked connection to port 80(even though the ports are forwarded).

Sudden Wifi Bandwidth Failure?

Nov 13, 2012

We pay for the 12 Mbps package from Comcast and speedtest.net shows that we get a roughly 18 - 19 Mbps connection. We have 4 computers connected to the network, one hard-lined and three wireless.

Usually it is not a problem for my roommate and I to play online games like TF2, Eve, Minecraft, L4D2 with C3 voice chat on our desktops while I simultaneously stream something from Netflix across my laptop.

Lately though, something has changed.

Now, whenever I am using my desktop and playing a game or downloading something (at roughly 2 Mbps) it seems to hog ALL of the bandwidth from the other computers on the network as Netflix suddenly begins having buffering issues on my laptop (wireless) and on my roommate's dektop.

As an example:

For the past few days my roommate and I have been trying to play Minecraft, we use C3 to voice chat while we play and I ALWAYS stream something across Netflix while we play. So in this instance we have one hard-lined connection and one wireless connection running Minecraft (across the LAN) and C3 (across the web) and one additional wireless connection streaming video from netflix (NOT HD Video).

This is common usage for us and it has NEVER been a problem in the past, but in the past few days this setup causes my desktop to lose bandwidth which forces my friend out of the game and causes latency issues with the voice chat program (sound breaks up and my roommate hears my voice chat nearly a minute after I've spoken).

Also, it seems that when my desktop (wireless) connection is working fine using around 2 Mbps, it seems to kill my laptop's (wireless) bandwidth and on one occasion the other night seemed to also affect my roommate's desktop (hard-lined) bandwidth while he was watching something on Netflix.

WNDR3700 Can't Access Router All Of Sudden

Jan 16, 2011

All of a sudden, I can't access my router. It's a Netgear WNDR3700. It's flawlessly, in fact still works flawlessly except I can't access it via 192.168.0.1. The only thing that has changed perhaps is that AT&T repair a DSL problem a few weeks ago, but they never touched my router.

Cabling / Cards :: Sudden Network Slowdown?

Apr 3, 2012

Three days ago people started complaining that it seemed slow. It's supposed to be 100mbps fully switched, but I'm getting speeds of 2mbps - 12mbps (at most) between two workstations on the same switch (which is just insane). I did happen to notice on a couple of the Mac OS X machines that the send and receive errors are off the charts (50% - 80% error rate)!!! This seems a bit suspicious to me.

Netgear WNR2000v2 - All Of The Sudden Certain Devices Cannot Connect?

Mar 11, 2013

Router: Netgear WNR2000v2

For a long time now, my router has been running fine with my devices. Now all of the sudden, some devices(my xbox, 3ds, and phone) cannot connect to the internet despite them picking up the signal. The weird thing is, the computers in my house and my PS3 can connect. I also don't think it's my security settings(TKIP and AES hybrid) since they all functioned fine with that before this problem.

I tried unsecuring my network as a test, but it seems that only my phone can connect while my 3ds cannot. I haven't tested this with the 360 however. I also tried resetting my router to factory defaults three times.

Cisco Routers :: Error 619 All Of The Sudden - VPN On RV042

Aug 3, 2012

a client of mine has a RV042 and uses it to work off site via PPTP server. It all worked fine until Friday, when it all of the sudden started spitting 619 errors saying the port was closed. The client laptop is a Window 7 Pro machine and we use the Windows VPN client to connect. I made no changes to router or client. I disabled the firewall on the client for one connection try, just to make sure and the outcome was the same. The setup of the PPTP server on router and the VPN connection on the client were so simple when I did it initially, that I'm now kinda lost and don't know how to troubleshoot it.We switched from QuickVPN to PPTP because we had a bunch of issues with QuickVPN and Windows 7 client is much faster.

Wireless :: All Of A Sudden The Network Began To Drop Randomly

Mar 15, 2011

Up until recently (4 months ago) my network was fine. However, all of a sudden the network began to drop randomly. Now, the network drops about every 30 mins. Its quite an inconvenience, especially as there are two laptops, a desktop and 2 games consoles running off of the network (not all at once though). I have a Belkin Wireless G Plus MIMO router.

Sudden Wireless Access On Belkin Modem / Router

Jul 28, 2012

My Belkin "ADSL 2+ Model with Wireless G" router suddenly stopped allowing wireless access this afternoon - right in the middle of use - although the wired connections to that router still work fine. No settings seem to have been changed on the router, and I'm the only one with access. Two phones and a laptop that normally work fine just won't get an connection. The laptop - running windows 7 - says the configuration saved did not match what the router was asking for. I tried another computer that doesn't normally connect by wireless and was prompted for a WEP key - which is odd because the router is configured for WPA/WPA2 AES access with a 9 character pre-shared key. After trying a key unsucessfully I haven't been able to get that prompt up again.Meanwhile I've gone into the router settings and it's definitely set to ask for WPA/WPA2. There are some WEP keys specified if I use the drop-down menu to select WEP, but I can't get any device to prompt me to enter one now.

Native Wifi Default Profile Sudden Appearance?

Dec 12, 2012

I have a Windows 7 64 bit computer that is connected to the internet through an ethernet cable to a 2-wire modem. Other computers at my home are connected wirelessly but I am not. I do have a NetGear print server and connect wirelessly with it to a printer. I am suddenly getting the notification "Native WiFi Default Profile Connected" even though I have been running the computer for a year without ever seeing this.

Is the wireless USB connection over-riding my ethernet connection? and is it possible to revert to having the ethernet connection be dominant? I prefer the ethernet connection for speed.

Cisco Switching/Routing :: Sudden Burst In Bandwidth 2911

Aug 8, 2012

The layout of the equipments are as such,other equipment <--> 2911 Router <--> Ether-Switch/3925 Router <--> 7206 <--> Internet,During certain times at night, the 2911 exhibits cpu load, high packet loss and an increase in bandwidth of at least twice it's normal amount. this results in packet loss in all the other equipment. I am attempting to locate who was demanding such a high burst but so far the graphs display normal rates for all the other equipment.Because the 2911 demands an increase from the 7206, the 7206 is able to accommodate this as it still has balance BUT my other equipment that are connected to the 7206 takes a drop in bandwidth as well. the graph shows that when the 7206 bursts higher, the rest of my other links take a slight drop in bandwidth.Also, the graph from Ether-switch to 2911 indicates the bandwidth hike BUT the graph from 2911 to ether-switch does not display the same thing as due to the cpu load, the data is somehow not captured properly.

Linksys Wireless Router :: E1000 Seems To Be Blocking Websites All Of A Sudden?

Oct 29, 2011

I am getting 404 messages but the browser is connecting to the site's server (you can see the little icon for each site in the tabs).  The two sites I have identified that I cannot access are UIowa libraries and Music from Outer Space.

-I have emptied all cache, cookies, etc.

-I have reset the router to factory defaults and updated the firmware

-I can load both sites from other networks, however two different computers using my router fail to load these two sites.Until a couple days ago I was able to access both of these sites regularly, and I haven't installed anything or changed any settings on my computer.The fact that two different computers cannot load these sites seems to indicate that it is a router problem.
