Weird home network issue (packet loss?) HELP!!!!

[jyml8582]

Greetings gents,

I've been having this issue with my home LAN for a week now, I've tried pretty much everything I know and still it doesn't even seem to resolve a bit. So I come here hoping to find the real experts who can remedy my agonizing problem...:(

My OS is Windows XP Pro SP2. I've run Avast! and Adware to make sure I am not infected by anything.

My ISP is Comcast. There are 3 desktop computers (mine is one of the 3) and 1 VoIP phone connects through a white Netgear 4-port wireless router to the Motorola modem. There are also addition 2 desktop computers downstairs, 1 laptop computer, and a Wii console that are connected through wireless.

All the devices have connections, except mine.

The weird part about it is, there is a working IP address (not the private one, but actual 192.168.x.x) assigned to my system by DHCP. I could ping to the router, Google, Yahoo, and CNN.com without any problem. But when I try to sign on to MSN Messenger or AIM, or open up Internet Explorer or Firefox to browse the web, I get no connections at all. The messengers would attempt to connect for a while before it quits, and the web browsers would show the little sand clock and the progress bar trying to connect, but eventually returns with "web site not found" page.

Since everything looks so normal, I did notice one thing that might be the cause of this loss of connection. When I opened up my local connections, and looked at the packet activity status. I'm seeing a large and fast increment of Sent packets, and barely anything for the Received packets. the Sent packets increases by approximately 100 packets/sec, and every 800 or 1000 packets sent there is only 1 packet received, and it gets slower and slower for the Received as this "activity" lasts.

I have tried power cycling the modem and router and my desktop. I shutted down my computer and unplugged both the modem and the router, then I waited for 30 seconds to plug the modem back on, waited til all 4 lights are solid lit then plugged the router back on, and then turned on my system. Same problem persisted.

I've then tried cloning my MAC address to the router, as suggested by one of the friends, but it just killed the whole home LAN.

I've tried the winsock solution as well, both the netsh> reset under command prompt and the Winsockxpfix.exe application. Didn't fix anything.

I've even tried going into my network adaptor to change the connection to 10BaseT half duplex (got it from some site as a solution for packet loss), still nothing.

It has been a week now and I've really ran out of things to try, I've contacted Comcast and when the guy tries to refer me to Microsoft I gave up hope on them.

Please help me...

hi.

firstly getting 192.168.x.x from dhcp is ok, it is still considered private ip, but others use the range 10.0.x.x ... anyway, i believe the problem is outside your router and broadband connection.... since other computers are not having problem aside yours....

kindly do the following... i assume you are to connect wireless

1. Go to Network Connections
2. Click on the Tab "Advanced"
3. Select " Advanced Settings..."
now this has two parts , Connections and Bindings for LAN
focus on the "Connection"
4. Select the "Wireless Network Connection" that you are using, then click on the UP arrow at the right hand side, to bring it farthest up. (you are just telling your computer to use this connection first)
5.then click OK


then try it...

***and also since you can ping to the internet try to put this
http://209.131.36.158/
on your browser(IE or firefox)..this is ip of yahoo.com. if you can surf using the IP, this is more of DNS problem on your computer.

Thank you for replying, genki.

My system has wired connection to the router...and I just tried the http://209.131.36.158/ in my IE6, and it did show the little sand clock on the lower left corner of the browser and the progress bar again, but then eventually it gave me "Page could not be displayed" message...

I did notice another thing...I hard reset the router several times, and ever time it's back on it picks my system first to manage the device, while all other systems are connected to the router as well. Still I have no connection whatsoever, and I had to unplug my cable from the router so that it finds the next working computer to set up the router...

After that I still have no connection...

Please let me know what other information I need to provide for further diagnosis, I will try my best to provide them here as I am close to desperate without internet connections.

Reset the router to factory defaults by holding the reset button down for 15 seconds with power on.

• Turn off everything, the modem, router, computer.
• Connect the modem to the router's WAN/Internet port.
• Connect the computer to one of the router's LAN/Network ports.
• Turn on the modem, wait for a steady connect light.
• Turn on the router, wait for two minutes.
• Boot the computer.

When the computer is completely booted, let's see this.

Start, Run, CMD to open a command prompt:

Type the following command:

IPCONFIG /ALL

Right click in the command window and choose Select All, then hit Enter.
