Internet Suddenly Slow


Recommended Posts

Okay, so just today I've started having problems with my connection. Instead of a 20 ping on one of my CSS servers, I get 200. Could this be because of my router? For some reason I get a worse signal with this router than with the old router (802.11b). I went to this website:

And got these results out of it

estimate = 2.74 based on packet size = 10Kbits, RTT = 255.99msec, and loss = 2.25938E-4

The theoretical network limit is 2.74 Mbps

The NDT server has a 8192.0 KByte buffer which limits the throughput to 250.01 Mbps

Your PC/Workstation has a 301.0 KByte buffer which limits the throughput to 9.21 Mbps

The network based flow control limits the throughput to 9.25 Mbps

 

Client Data reports link is 'Ethernet', Client Acks report link is 'Ethernet'

Server Data reports link is '10 Gig', Server Acks report link is 'Ethernet'

 

I am using Verizon FIOS 15Mbps down, 2Mbps up. Router is D-link DI-524, wireless card is D-Link DWL-G510.

Did you run a spyware check like updated adaware and search and destroy? Sounds like a malware problem to me. Also you can try to reinstall your network card drivers, restart your modem, repair the connection in network connections page, etc.

Yep, ran spyware checks. Also, the thing with restarting the modem... I'm not sure where the modem is. They installed a box on the outside of the house, with some battery pack somewheere and it is connected in some manner to the powerlines. I'll try out the other suggestions though.

Your wireless card in your pc "talks" with a modem. You may have a home networking modem installed on a wall or something, but usually they are something that looks like this : 3245_MotImage.jpg. Find a reset button on it, or alternatly navigate to your modem settings page in your browser and reset it from there. If you dont have any spyware a fresh connection to your isp should solve the slowness. Search google for your modems settings page address. mine is "http://launchmodem" for bellsouth fastaccess ultra, but yours may just be an http://xxx.xxx.xxx.xxx isp number.

Who's your ISP? I've had SBC slow down on me recently, get ping mountains more and more often (as opposed to spikes)

 

If you have comcast, call support and they will probably try resolving it, assuming what i've heard from a different customer is true.

I've tried a lot of different things with my network card and internet modem too, but I still have problems. Like OptikaliLLusion, my ping on my favorite CS:S servers was in the 40s, but now ranges from 300-900 with insane spikes. I think the problem is that your connection is becoming hogged by other people. For me, my bro is using my wireless router to connect to the internet (I have a RangeMax WPN824 wireless router). What's a better way to hog the internet connection than when he plays WoW. The unfortunate part is that I don't know how to limit his bandwidth consumption, so I'm stuck with the high pings until I can figure a way out.
