I am facing a strange issue here. I am connected to BSNL broadband through a W3002G4. After I switch on my modem and the laptop, I try to connect my laptop on wireless, but my internet connection does not show up (thought it shows some stray signals). Then I connect it with a LAN cable and I am able to connect to internet.I open the modem config page (192.168.1.1), disable my wireless and re-enable it. After this my laptop detects my internet connection and I am able to connect to it. I disconnect my LAN and then the wireless works fine afterards. I am using WPA-PSK for encryption. Wired internet works fine for my desktop as well as laptop. Please help...

Recheck wireless settings :
Chennai Telephones- Changing password in DataOne Pre-configured modem

post ipconfig /all
Start run type cmd type ipconfig /all

Looks like my wireless does not want to take the IP 192.168.1.2 which it is forced to take when I am not using any wired connections. Modem configurations are all fine. I will post the required command outputs, in the meantime, if I have to set my IP manually, what do I use for preferred DNS and alternate DNS?

superprash2003

use opendns servers 208.67.222.222 and 208.67.220.220

I want to do it MANUALLY!!!!

essbebe

1.Check ipconfig /all of

2.your desktop

3.and laptop in WIFi mode.

They should be different.

4.In modem router select DHCP enabled
Give range 192.168.1.2 to say 192.168.1.6.
Enter IP within this range in desktop and laptop.

I found somethng pretty interesting....my wireless works fine if I am initially connected by LAN. Eg. I connect my desktop with the modem (wired LAN) and switch both of them on and internet is working fine.I switch on my laptop and it detects my modem (wireless) and works fine, even after disconnecting my desktop from the modem. But my laptop would not detect if I just switch on my modem and my laptop and try to connect wireless.Infact I dont even have to switch on my desktop to get the above thing working (if power is given to ur motherboard and ur modem is connected to ur eth card ur modem will show eth connected even without switching on the desktop). Can it be a laptop issue? both my laptops having the same issue.

@kaudey


1.Are you using a "Dialer" In desktop to connect ?

2. If so, in wan Page disable "Bridged" and select
PPP/PPPoE. etc Save/ Reboot
( enter userId without @ bsnl.in )

3. . When all are connected to Internet
post these data for each.
ipconfig /all
Start run type cmd type ipconfig /all

i had a similar issue with a netgear once , wireless would pop up only when wired is connected , it turned out to be a firmware issue , but the best part about netgear is that everytime they launch a new firmware for a model , they tell you why they do so , what bugs they've fixed etc , so it was easy for me to debug, but i dont think your wifi router company would provide such details..

No I am not using a dialer, i connect through pppoe.here is the IPconfig /all from my laptop:

I have disabled the DHCP on my router.

essbebe

@kaudey
enable DHCP in router.

Any particular reason: you want to disable DHCP?

kaudey

I was just trying stuffs...I have enabled it now. But wht is the use of having it enabled if the IPs are assigned manually?

essbebe

post No 6.
Because you wanted to enter them manually.

Now please give feed back whether
desktop laptop all access Internet
without any problem.

kaudey

Sir, I never had problem accessing internet (wired or wireless) I just had some starting issues...OK I will explain once more.

-I switch on my modem (no LAN connection is there) and I switch on my laptop.
-Unable to connect to wireless, my SSID is not even showing up in available wireless networks.
-I connect laptop and modem with LAN (obviously able to access internet now) and go to 192.168.1.1 -> wireless -> disable wireless->save->enable wireless->save.
-Bingo!!!wireless shows up and connects nicely
-disconnect LAN and now able to work with wireless without any issues.

Alternatively:

-switch on my modem (my desktop is connected through LAN), wireless is enabled
-switch on my laptop. Bingo!!! I am able to connect wireless.

it does not matter if I switch on my desktop or not but if a LAN is detected by modem (i.e. either of the LAN1,2,3 or 4 is glowing) my wireless works fine.

I hope it was easy enough to understand

REF:
The little I know about Dataone Broadband Services offered by BSNL
(1)
for rechecking your wireless settings in WA3002-g4.

(2) my default value in wireless LAN card. see Annexure.
Check yours in both laptops.
select "ssid" and try.

I am sorry but which annexure are you talking about? I have checked my router settings again...nothing much different.
