Thread: Configure Airtel through Wireless router

Dear All

We have Small Office Network with 5 Laptops. We Planned to Use wireless router for LAN purpose and internet Connection.

Please give me a suggesion to design my network.

What is the iprange I have to choose. What is the ipaddress I have to give in Airtel modem, Wireless router, & Laptops.

What is the difference beween PPPoE and Bridge. Which mode of connection gives efficient output to my Network.

Expecting your Answres.

5 Laptops - For Internet & Lan Connection.

It is possible to configure your wireless router to get 5 laptops to be networked with Internet facility.

=====================
What is the iprange I have to choose. What is the ipaddress I have to give in Airtel modem, Wireless router, & Laptops.

If your airtel broadband connection is on a PPPoE/Bridging...No issues connect it with the router...

Like

Airtel Modem ---> Wireless Router ---> PC (Connect theses devices using hard wired accordingly)

If suppose your Modem & Wireless Router have same gateway, then it is issue. At this situation, You need to change the ip address on the Router.
then it will work fine.

=================================================


PPPoE/Bridging are the two technics...in general...it is for authentication. In my experience...there is no co-relation between them...Either will do

Sorry for delayed reply, because i have joined only today....

At our office we have a corporate VPN connection.

Layout is as below

Leased Line->Router->Switch->User PCs (With Static IPs in the series 10.10.64.*)

We have airtel internet connection with Beetel 220X Modem.

Kindly suggest how to connect the airtel connection so that all the users can simultaneously use Office VPN & Internet.

From your basic network diagram, I would presume that the PCs are currently hardwired to your switch and have static IP adresses assigned to them in the 10.10.64.0 range.

In this case, you have two options:

1. Connect the Beetel modem to your switch. Add routes to your router to route all route all internet traffic to the Beetel modem which typically has an IP adress of 192.168.1.1 by default. This in my opinion would be the easiest and most cost effective way to handle both VPN and Web access for you, but requires some changes to your routing tables. If you are uncomfortable with changes to your routing tables then the read the next option.

2. Attach a wireless router to your Beetel modem. I presume all your PCs have appropriate wireless adaptors in them, otherwise install wireless NICs in the PCs. The wireless router settings would be as follows:

1. Router IP - 192.168.0.1 ( Actually you could use any of the private ranges except 192.168.1.0)
2. DHCP address range - 192.168.0.10 - 192.168.0.254 ( change this if you are using any other address in 1 above)
3. Wireless Security - WPA2/TKIP Preshared Key. Please choose your preshared key carefully and try not to use any dictionary words...
4. Connection Type - IP assigned by ISP
5. DNS - enter your DNS server IP addresses. In case you have a problem, add the open DNS server IPs (208.67.222.222 / 208.67.220.220) which according to me are much more reliable than the Airtel DNS servers
5. Be sure to change the default password on the wireless router!!!

Settings on the client PCs should be simple - Just set them to obtain the IP automatically and input the pre shared key and you should be set to go...

Let me know if you need anymore help on this...
