This one really has me all but stumped. They don't play with your line out east. All i can think of is the salty air has corroded some wires somewhere and the wind is playing a part by swinging the wire. That's about the only thing that could explain the *selective* packet loss.

Basically dabbles some registry values to reduce lag.
You can also do it manually by going into regedit & follow these instructions..

Smart fix allows you to drop your ping by 150

The fix which only requires you to change 2 small things in the windows registry allows your ping in World of Warcraft to drop by 100-150, and it only takes about 5 minutes to apply.

This fix has been circulating trough various forums for a while, and at first I must say I was a little sceptical about it actually working, but after I heard several friends who tried it successfully, I had to give it a shot and it actually lowered my 200 ping on the European realms to about 70. Basically it's deactivating the nagle algorithm to improve your ping.
Step 1 - TcpAckFrequency
NOTE if you are running Windows Vista this setting may not have any effect - a hotfix is needed which i'm tracking down. This works fine under Windows XP
Type "regedit" in windows "run.." dialog to bring up registry menu
Then find:
HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Servic
es\Tcpip\Parameters\Interfaces\

There will be multiple NIC interfaces listed in there, find the one you use to connect to the internet, there will be several interfaces listed (they have long names like {7DBA6DCA-FFE8-4002-A28F-4D2B57AE8383}. Click each one, the right one will have lots of settings in it and you will see your machines IP address listed there somewhere. Right-click in the right hand pane and add a new DWORD value, name it TcpAckFrequency, then right click the entry and click Modify and assign a value of 1.

You can change it back to 2 (default) at a later stage if it affects your other TCP application performance. it tells windows how many TCP packets to wait before sending ACK. if the value is 1, windows will send ACK every time it receives a TCP package.

Step 2 - TCPNoDelay
This one is pretty simple (Discussed here)
Type "regedit" in windows "run.." dialog to bring up registry menu
Then find:
HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\MSMQ\Paramet
ers
Right-click in the right hand pane and add a new DWORD value, name it TCPNoDelay, then right click the entry and click Modify and assign a value of 1.
Click Ok and close the registry editor, then reboot your PC.

If you're using wireless, ALSO make sure that your channel is clean. Try switching from the default channel on your wireless to 9 or 11 or even as low as 5 or 7. Get away from the current one, as most people never change it from the default for their router (and it's usually the same), so you could easily see it getting filled up with a lot of other people's traffic  
----------------------
A reason you could have a bad connection is that you're downloading something & its taking up bandwidth, or maybe someone in your house is downloading something.
Worst case scenario if nothing fixes it try switching your ISP.
------------------------
The only way you can get a workaround is to phone your ISP and ask them specifically to change your link onto a less populated one, or to ask them to look into traffic shaping. (This involves using WireShark or similar program/s to flag internet packets as games / p2p / streaming etc, and give priority to the most important.) In this case that would be gaming.

E4200V2 slowness that goes away after reboot 

01-21-2012

Do the following steps:

A] With the help of Cisco Connect Software (if at all you have installed the router with the help of this software)
1] Open the software and go to the option which says "Router Settings"
2] Then click on the option which says "Advanced Settings" which will take you to the router's configuration page.
3] Lower the MTU (Maximum Transmission Unit) from 1500 to 1400 or less (usually found on your router's main/ basic setup page)
4] Then click on Security tab disable SPI Firewall Protection, un-check Filter Anonymous Internet Requests...

B] If you haven't installed Cisco Connect then you can log on to the router's user interface using it's default IP address in the browser which is 192.168.1.1 and type in 'admin' as the password leaving the user name field blank. This will take you to the router's web interface and then follow steps as mentioned above to make the changes.

Then check the connectivity..
