Thread: Lan not working where as Wifi works

I have a Airtel Broadband connection with Beetel 45 BXI ADSL2 + Router. Wifi works fine with both my Laptop ( XP and Windows 7). Where as when i connect using lan the connection does not come up at all. It always says identifying network when i use automatically obtain ip address. Even when i use static ip address i am unable to ping my default gateway. Even in my desktop lan connectivity is not working. I used both straight cable ( this is the correct one to be used) as well as cross cable.

Whereas when i use wired connection at office it works fine in my windows 7 laptop.

Please help. Are there any setting that need to be done on the modem to make the lan connectivity working.

If wifi mode router is working WAN settings are Ok.
You can check the diagnostics page and confirm.
SEE wa33002-G4 quick guide ( recheck buttons in WAN page)
Check in Network/ LAN/Properties
On top ethernet card box select configure
enabled.? Advanced check driver etc.
Click the LAN Icon in Taskbar try diagnose what is the error message. ( windows 7 system )

Still no connection in lan mode
post ipconfig /all data. as attachment .*.doc.
Mention OS used.


Feedback.

Could it because of the fact that the modem is 10 mbps and all the lan cards in my system have 1 gps capability. do we need to hard code the system lan card to 10 mbps full or half duplex. Anyway i will carry out all the test and attach tem to the thread.

If you had posted ipconfig /all data,
I would have got details of the LAN ethernet card used.
and any error in settings in your system for lan mode.

Attaching the data that you have requested.

Attaching the data from the Desktop. The earlier file was from Laptop. I do not have any wireless card in my Desktop. OS in my Desktop is Windows Home 64 bit.

Hope this helps in finding what is the problems. Thanks in advance for your help.

Sorry. cannot help you further. You are using a newer version of WORD>
I don't want to "download a compatibility file of 37 MB ( from Microsoft) to read your attachment.

Sorry did not realise that. Re attaching after saving it with .doc extension.

Check your WLAN settings. Ip address will be 192.168.1.X
( as given in your router DHCP enabled lan page)
Subnet should be same 255.255.255.0
gateway will be 192.168.1.1 ( modem address )

In Lan network Instead of Obtain Ip address automatically
enter 192.168.1. Y ( different to WLAN Ip address )
All done TRY Diagnose and give error message if not working.

Still Not working. in addition to what you mentioned i also tried playing around with the speed under the configure tab. No luck at all. Not sure what is missing. This is a brand new Dell XPS Desktop. Attaching the file as requested by you.

Whereas when i use wired connection at office it works fine in my windows 7 laptop

.
Which means no problem with the ethernet card./ Dell Laptop.
Recheck tomorrow with present settings !! & confirm.
What kind of connection in your office lan ?ISP ?
wait.....
Now the modem/router settings are suspect.
Are you using Dialer Mode or PPPoE "Always On" mode ?
Appears you are on PPPoE mode and check in WAN page , where you enter USERID/PW last button is selected some "bridge...... etc "
LAN page DHCP enabled ? range given ?
Check Diagnostics for line 0_35.

or
On line check of modem/router settings :
http://checkip.dyndns.com/ say 117.xx.x.xx
post it here confirm Modem access admin PW password
After I check restart the modem.

Current IP Address: 122.166.161.119

You are right about the username and password.

I did not understand what you meant by

Check Diagnostics for line 0_35

System log is empty. Do i have to configure anything to generate system log.

Attaching screen shots of modem settings.

sorry. Dinner. unable to open IP given by you
wait......

np. Take your time.Let me disconnect my VPN.

Current IP Address: 122.166.161.119

Appears you are behind a firewall. unable to access. not needed now.
In Office you connect in VPN mode on a different BB connection
automatically. with a different ID PW.
Check in Network settings the name allotted.
Confirm you use the same Modem/router Beetel450BXI.

2.
Now in your house you have to use your modem with Airtel allotted Id & PW, (and confirmed connected In WIFI mode. )
Check the SSID name appearing in Router is same what appears in your laptop.Do you use any security key ?
In modem menu ( In LAN Mode) Click Diagnostics menu.
give details here.

Check settings similar model

I am not aware of any firewall.

The SSID in Laptop is same as i am using in Router.

Network Authentication is Open and I am using WEP Encryption with a encryption of 64 bit.

These settings are for wireless right would it cause problem for Lan connectivity. My Wireless connection is working fine where as only Lan is not working at home.

(1)Do you have an Airtel Broadband connection at Home with your own
Phone number for personal use ?
(2)and also access VPN network, immediately from HOME ? Do you use a dialer?
(3)
( In Basic menu Can you disable the Wireless and try ?
(4)
All settings appear O.K.

Yes i have a Airtel connection (4 mbps ,unlimited plan )at home for my personal use. From home i connect to my office network using VPN.

Not sure if the problem was there before for Lan as i always use wireless. Recently i bought a desktop for my son and in that also i am not able to connect . That is when i checked my laptop as well it does not work when using lan. My both laptop (office and personal) as well as the desktop does not work when using lan. I have ordered for a wireless adapter for desktop.

Appreciate you help. Not sure what could be wrong. Do you think changing modem will help.

If i disable wireless then i will have no means to connect to the modem as Lan connections are not at all working. Then i will completely loose connectivity.

(7) UPDATE
In your lan page deselect IGMP and Block buttons.

select middle button only standard mode.
SAVE REBOOT.

Just to confirm that my lan card does not have any problems. I went to my neighbor's house whose has a BSNL connection. There i have no problems at all. I am posting from his house there the lan connection is working. Some problem with my Airtel Modem connection only.

If i disable wireless then i will have no means to connect to the modem as Lan connections are not at all working. Then i will completely loose connectivity.

I use Cisco VPN Client to connect to my office network.

see my post again updated.
LAN page entries.

I am seeing the same when i checked my neighbor's BSNL setting there also i am seeing the same setting as posted by you in the screenshot. I will try disabling IGMP snooping.

Still no luck. .....

Recheck the page whether the changes were made.. are Ok.
When you switch on the modem do you get connected in WIFI mode
automatically now ?
