FAQ's About Wireless Broadband and Routers

[paul]

Whether using proxy servers is good to process incoming and outgoing voice data? Because security breaches are high in VoIP and any such threat may bring down voice and data networks in worst case. Also I heard, by segmenting of voice and data traffic using a VLAN's would minimize threat and diminish chances of disruption posed by packet-sniffing tools.

Thanks for the detail and configuration advice, however I've to check some of the issues with my service providers and as well as the configuration and network architecture. Can you suggest me any performance-based model website that provide user review too in the line of VOIP/ Wireless related products and services?

"Limited or No Connectivity"

Limited or No connectivity:

One of the reasons for that to happen is:

You get this message after you have installed Windows Xp service pack 2, this will not let you access the internet or some network resources.

There are many solutions for the same, and most of them just bullshit you and ask you to turn off this notification. But its only good if if its a false message, but if the system has really lost LAN connectivity or if it is unstable then you are in trouble.

Also does not help you to go and ask your ISP for the same, believe i have worked for them and they will give you all the crap in the world. So this would help them as well.

It is due to a bug in the Service pack 2 of windows xp

One solution is patching for this bug,or you may have to reinstall your firewall,rebuild the configuration of your router,drop the connection speed of you connection from 100 Mbps to 10 Mbps,or in case of a network assign a dedicated IP to your computer in the network.

Symptoms that your system is affected by this bug:

1) After installing Windows service pack 2 your network starts reporting "Limited or No Connectivity".

2) You are not able to connect to the internet or your LAN after installing Windows service pack 2.

3) Your network gets stuck while "Acquiring IP Address"

Solution:

Download the patch you can download a zip file with the patch, registry file, and instructions by clicking here.

Run the patch and install it.

Run this short Registry fix to complete the update. Type the following lines in Notepad and save the file as FixReg.reg on your desktop, then double click on it to install into your registry.

Windows Registry Editor Version 5.00

[HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Servic es\IPSec]
"AssumeUDPEncapsulationContextOnSendRule"=dword:00 000002

Reboot the PC

If the error message pops up again, reboot you PC first.

If you want to disable the message after the problem is fixed:

Open Control panel >>> Open Network Connections and Right Click on the Local Area Connection and click on Properties >>> Uncheck the following option on the General Tab >>> "Notify me when this connection has limited or no connectivity"

Again if running the patch does not resolve the issue:

1) Your network or your Router may have some error on it. Power recycle the router or reconfigure your router.

2) Check the cabling for your router, straight-through CAT 5 or possibly a crossover cable and try another cable.

3) check your Network card and make sure its configured properly. Try and change the settings for the network card to 10Mbps/full Duplex to solve the issue. To do this open Control panel >>> Device Manager >>> properties of the Network card >>> click on the Advanced tab >>> find the Link Speed and Duplex section >>> Change from Auto Detect to 10Mbps/Full Duplex.

4) Check your firewall, especially if its Zone alarm, Black Ice, Nortan Firewall. Disable your firewall and test your connection. You may also have to uninstall and reinstall your firewall.

5) Reset your TCP/IP stack by downloading and running WinsockXPFix.exe a Visual Basic program designed to fix corrupted TCP/IP issues, host file problems and a variety of other connectivity issues.

What will the Winsocfix Utility Do for your PC:
· Detect your current Operating System
· Release the IP address, taking you "Offline"
· Reset the TCP stack using Netsh.exe (Windows XP only)
· Delete the current Registry TCP and Winsock Values
· Import new "Working" Registry Values
· Backup any Current "Hosts" file
· Replace the "Hosts" file with a default one
· Reboot the Computer

6) If connecting to your network using Wi-Fi and using wireless security, your WEP or other security key may not be set properly. Check the wireless security configuration on your computer's network adapter and update if it necessary.

7) If using a broadband router and DHCP on your network, check your computer's IP address to verify it is valid and not a private address that starts with 169.254. An invalid address of the form 169.254.x.x signifies your computer's inability to obtain a usable IP address from your router.


Hope this helps, and if you need any further help just update the post for me

[Jedi-Brad]

I would suggest you to use the LInksys WRT54GP2-NA or the D-link DVG-1120.

THe configuration for the DVG-1120 is as follows:

Asterisk mgcp.conf settings (1120M)


[000abcdef12] ; device's mac address
host = dynamic
context = from inside
canreinvite = no
[email protected]
nat=yes
threewaycalling = yes
transfer = no
callwaiting = yes
callerid="Line 2" <14165551213>
line => aaln/2
context = from-inside
[email protected]
threewaycalling = yes
transfer = no
callwaiting = yes
nat=yes
callerid="Line 1" <14165551212>
line => aaln/1
line => *

Asterisk sip.conf Settings


[1020]
username=1020
type=friend
secret=SECRET
qualify=no
port=5061
nat=never
host=dynamic
dtmfmode=inband
context=internal
canreinvite=no
callerid="1020"<1020>

Note: The CID name inside quotes on "caller id" must correspond to the "display name" field on the VoIP router's page below.



Hope this helps

Very informative article, I would like suggestion what would be best for me if I use VOIP, I rather considered to use separate Linksys PAP2 for my VOIP needs, and let the current router do the routing as it is.

Wardriving, Warbiking, Warwalking and Warkiting

Wardriving; named after the wardriving term used in the 1983 film Wargames.

Basically its searching for a unsecured wireless network on the move (moving vehicle) using a PDA or Laptop.

There are various software's available for the same for e.g NetStumbler for Windows, Kismet or SWScanner for Linux, FreeBSD, NetBSD, OpenBSD, DragonFly BSD, and Solaris, and KisMac for Macintosh.

Warbiking; It same as wardriving but here the mode of transport is moving bicycle or motorcycle.

Warwalking; here its done while you are on foot rather than on a moving vehicle.

Warkiting; it a combination of wardriving and rootkitting. In warkitting the hacker chnages the firmware of the hacked routerand controls the complete traffic of the victim.

I think all the above are used for unethical purpose; the latest was used by terrorist in India during the recent serial bombings.

How do i connect My PDA to my Broadband?

Yeah its possible to do the same all you need is a Bluetooth Access Point for e.g D-link DBT-900AP. It will plug into the spare Ethernet port on the Router. Also you don't need your PC to be switched on for the same.

Difference between 3G Data Card and a Wireless Networking Adapter?

A 3G Data card will connect to your Laptop and is a PCMCIA Card. It enables you to connect to 3G mobile Phones / Data Network.

A Wireless Networking Adapter enables you to connect to a Wireless Network within the Range (Your Broadband Connection)

The benefits of 3G Data Card is that it enables connectivity in large parts of UK. Also it enables you to Switch over to GPRS where ever yo don't find 3G coverage. This is not possible with Wireless Networking Adapter as you have to near a Hotspot or local access point. Not helpful if you are on the move.

The only benefit of the Wireless Networking Adapter over 3G Data Card is that the Speed available with the WNA is more than 3G Data Card. Also the cost of 3G Data Card is more.(cost of the card, monthly fees and bandwidth costs)

Wireless Networking Adapter 2Mbps to 54Mbps (limited to availability)
3G Data Card 384Kbps



Orange 3G Data Card



Vodafone 3G Data Card

Nice thread!

I prefer the Hauppauge TV tuners as I have found they work best here in the UK. I use one on my PC, and I find it works better than any others I have tried.

How to connect My Game Consoles using Wi-Fi to Internet?

For this you need wireless router with integrated modem, The router would establish the connection wirelessly to your console. and you can connect your PC to your router using Ethernet cable or USB adapter.

However if you want to use your USB modem (such as Speedtouch 330 by Tiscali and Toucan)to connect your Console (such as a Wii, PlayStation 3 or Xbox 360 with wireless adapter) you need a wireless adapter on your PC to create an Ad-Hoc type Connection. The only downside of this method is that you would need your PC to be switched on for you to connect.

So the first method is always advisable.
