How to add new Internet Time Synchronization servers to Windows XP.


Serious Note:

Modifying the registry can cause serious problems that may require you to reinstall your Windows. Use this information provided at your own risk.

To add more time synchronization servers, find this registry key below.

[HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\DateTime\Servers]


Add these other “strings” into that registry location.
Backup your registry and be careful not to input bad data values, check your work when done is my motto.

------------------------------------
Default = 1 ----- (((Do not change this value; it is only the server you are using now.))) -----

1 = time.windows.com
2 = time.nist.gov

----- (((Do not enter these instructions into the registry.

{You will create these other strings then name them, afterwards enter the server data; when done it should look exactly like this below.} ))) -----

3 = time-a.nist.gov
4 = time-b.nist.gov
5 = lerc-dns.lerc.nasa.gov
6 = wwvb.isi.edu
7 = bonehed.lcs.mit.edu
8 = bitsy.mit.edu
9 = clock.osf.org
10 = navobs1.usnogps.navy.mil

----- Now close the registry editor and you are done, those new servers will now show up in the server synchronization choices list shown above. -----

How to Connect 2 Wireless Routers as Wirelessly

Hello Everyone,

Today, I have an interesting topic to share with you guys.
It is How to Connect between 2 Wireless routers (or more) as wirelessly to extend the existing Wi-Fi network. It is a really sweet solution for a certain company who wants to have strong wireless connection and wired switches in a large sharing space between their host PCs, and who is not possible to have any further installation of CAT5e Connection on the wall due to their limited expenses.

(You may say how about just using the Wi-Fi expander???) - it may help some different issues but not enough solution sometimes.

The above solution for the topic is really possible but there are some limitation unfortunately.

1. You have to use "Linksys WRT54G" router family only.
2. You have to obtain and to upgrade "Open Source (hacked) Firmware for the routers . Due to Original Firmware doesn't have the required function(is called WDS(Wireless Distribution Serivce) to setup what we want. ) - It might be illegal, so be careful!!!

Once these two requirements are satisfied, you are ready to go to fun.

How to Setup?

1. You have to obtain the hacked firmware first and apply on to all WRT54G wireless routers.
2. The routers must have in the same subnet range and in the same wireless channel.
3. Setup AP1 with main gateway for your ISP Connection and DHCP on.
4. Setup SSID and no Encryption (it will be done after WDS connection verified)
5. Setup AP2 (and other APs) with DHCP off.
6. SSID setup could be different name and check Wireless MAC Address.
7. Setup each AP's IP Address diffferent from AP1 but the Gateway is the same as AP1.
8. On AP1, Put the AP2 (or all other APs) MAC Address on WDS settings with each AP's SSID.
9. On Ap2( or all other APs), put only main AP1's MAC Address on WDS settings with AP1's SSID.
10. Setup the Encryption after verifying WDS connection between all Wireless APs.

Then, enjoy your Wi-fi extention.

The below image is an example of the possible connection.
