Packet Loss Situation (EXPERIENCED)

post #1 of 11
Thread Starter 
If someone can figure this out, props to you, seriously. Here;s the situation:

PS: This is a CABLE connection, 20mb down 1mb up.

Playing World of Warcraft April 18th 1:00am
Disconnect, can't reconnect.
Pingtest -> 75% packet loss

April 19th 1:00PM
Tried calling ISP, not from their end.
Tried Ping test on PC #1 while other PC's are shutdown, 23% packet loss
Tried Ping test on PC #2 while other PC's are shutdown, 30+% packet loss
Tried Ping test on LAPTOP while other PC's are shutdown, ~40% packet loss

PC# 1 and 2 running on fresh install of Windows 8 Consumer Preview.
LAPTOP running on 1 month old install of Dell Windows 7 ( New Laptop )

Did a full reset to factory settings on modem. It is a MOTOROLA SBG6580 all-in-one.
I have no router hooked up.
I did a system restore on the LAPTOP to make sure it hadn't had anything installed last night that could of hindered the connection.

PC# 2 and LAPTOP have a really hard time opening browsers.
PC# 1 doesn't seem to be struggling at all.

I did the CMD - > ping www.google.ca -t on all computers, ~30% packet loss on all of them.
Looked for new drivers for the Ethernet cards, nothing.

This happened last night all of the sudden and for no reason.
Anyone have ideas?

since all three pc's are getting ~30% packet loss, and the ISP says its not them, i'd guess that the modem might be dying. do a tracert, and a pathping to get a better idea. Here's a guide to using tracert to debug networks and track down packet loss. tl;dr version, if the packet drops happen in the first 1-2 hops, it's probably the modem. hope this helps you figure out where the problem is.

Sounds like your router is just getting overloaded, time to upgrade. Those modem's/Routers are never really a good idea unless you are a very limited user.
post #4 of 11
are the packet losses random or sequential?

Also have you got another router you could try it one to takeit out of the equation?

Did you try a new Cat5/e cable? Also in Dev man, under the NIC try setting Speed/Duplex to 10/half duplex. Let us know.

Changing the cables wouldn't do anything, as stated, packet loss is present on 3 different computers, including a laptop on wireless.

Secondly, no I cannot change the router, as I've stated in the main post, it is a modem/router all-in-one, which is provided by the ISP. So I cannot change it unless I call them and order another one.

And sadly all they have are 2 different models of the Motorola, one that's just modem and then the one I have have. (All-in-one)

Just so it's clear, when I ping a website through CMD, it can ping fine ~ 20 times then starts droping like crazy.

The tracert doesn't seem to have anything unsual which is really weird.

Notices the tracert to www.mmo-champion.com on hop 9 has an asterix.
Now I am wondering if it really is the router.

I am also gonna try and change the duplex, I am in Windows 8 so i'll update soon. More help apreciated.

Thanks!

I thought I 'd also add that I've done a tracert through CMD and I get way more asterix and drop outs.

have all the nodes on your network got different IP addresses?

Of course.
post #10 of 11
What if you ping a local computer, say computer 1 to 2? Do you have the packet loss then? Also, what was the IP on hop 9? It is cut off in the image, and I wanted to see what my results to it look like, I can get to your hop 5 without issue.

The duplex won't help I do not believe, I misread the first post, along with missing that the modem is an AIO. Today was a long day at work.
