Linksys WAG354G remote management access of router

Hi

I am attempting to administer my daughters Linksys WAG354G modem
remotely.

The manual is quite vague. Any help would be appreciated.

Manual says:

The Administration Tab / The Management Tab
·To enable Remote Management, click Enable.
· Management Port. Enter the port number you will use to remotely
access the Gateway.
· Allowed IP. Specify the IP address(es) allowed to remotely manage
the Gateway.

I presume I enter my IP address, what port do I choose - 8080 or
something else.

How do I find the IP address of the router? (I am sure it is in the
manual, but can't find it).

Do I then enter the router IP address and port No in my browser like:

eg: http://24.2.36.xxx:8080/ then password when requested?

If the above is correct, is there anything else I should know?

Thanks ColinK

1. The router may be set up to allow admin access only via a wired
connection (ie not wiireless). This is safest option anyway - 3rd
parties can't reconfigure your router.

2. Even if it is set up to allow wireless administration, if you mess up
the configuration then you'll probably need to connect wired anyway to
fix it.

3. The router IP address is probably on the bottom of the router. It
also lists the default username and password.
My Linksys router (not the same model as your's) IP address is
192.168.1.1 port address is 80
so just enter 192.168.1.1 in your browser address bar.

4. You could TEMPORARILY disable the firewall to check that it isn't
blocking your connection.

Hi

Thanks for your suggestions.

The router is configured for wirless management. I have since found out
that someone else in the building has plugged in a wired connection
(without permission) and I believe the internet connection stoped then.

As far as I know this user did not change any admin settings. He did
disconnect from the mains and restarted.

Any ideas what could have been wrong with his NIC that could have
caused intenet access to fail?

Am I correct that disconnecting then mains will not have changed the
ISP settings for username and password?

Is the I address 192.168.1.1 not the default address to access admin
directly at the modem (it is the same as mine). Surely I will need a
unique IP address to access the modem remotely?

Thanks Colin K

I think you are correct here.

The following info is from my own WAG354G.

REMOTE MANAGEMENT.

This feature allows you to manage your Gateway from a remote location,
via the Internet. To disable this feature, keep the default setting,
Disable. To enable this feature, select Enable, and use the specified
port (default is 8080) on your PC to remotely manage the Gateway. You
must also change the Gateway's default password to one of your own, if
you haven't already. A unique password will increase security.

To remotely manage the Gateway, enter http://xxx.xxx.xxx.xxx:8080 (the
x's represent the Gateway's Internet IP address, and 8080 represents
the specified port) in your web browser's Address field. You will be
asked for the Gateway's password. After successfully entering the
password, you will be able to access the Gateway's web-based utility.

Note: If the Remote Management feature is enabled, anyone who knows
the Gateway's Internet IP address and password will be able to alter
the Gateway's settings.

I think we need to establish exactly what the OP wants to achieve.

My understanding is that ColinK is at "Location A" and has internet access.

His Daughter is at "Location B" (presumably in another city) and has the
Linksys WAG354G router. Daughter connects to router using wireless.
Daughter now cannot get internet access. A third party was involved
(perhaps innocently !?!) at the time when internet access disappeared.

ColinK will not be able to manage the router remotely unless he
pre-configured it to allow the facility. He therefore cannot fix the
problem.

Solution: Daughter must connect her computer to the router using an
ethernet cable, and open the management page on the router. Daughter can
then correct the router settings to allow internet access. Daughter might
be able to configure router to allow ColinK to have remote managment
access - this depends on several parameters:

1) The router must have a working internet connection

2) ColinK needs to know the external IP address of the router. The ISP
might provide a static IP address - if so, use it. But for domestic ADSL
this is unlikely. So the router must be configured to use a Dynamic DNS
service to report its current IP address to the DDNS service. This requires
pre-configuration of the router with these details, and the setup of an
account with a DDNS service provider - there are free providers which would
be suitable. If ColinK cannot set this up and talk his daughter through it,
she could ship the router to him.

3) The router must be configured to allow managment from the internet. Some
will allow this from any address; others will only allow external management
from one (or a small number) of named addresses. So depending on the router
ColinK might need to have a static IP address at his home also.

4) The router should have a management password set. This will ensure that
casual connections from the LAN cannot gain access to change the
configuration. It also protects WAN-side connections if the security
measures in Step 3 don't already provide sufficient security.

Of course, there is nothing to prevent a (malicious) third party from
resetting the router if he can get physical access to it. However, given
the correct preparation, Daughter can be talked through reconfiguring the
router provided she can connect to the router with a cable. This would be
simplified by saving the router's configuration on Daughter's computer.

Note: I have seen routers "forget" their configuration. On one occasion,
simply by being powered off for 10 days (a Sweex router); but more generally
by a blip in the mains caused by a nearby lightning strike. So the Daughter
*must* be able to reconfigure the router herself, and should be provided
with the necessary tools and training. Or she needs to find a trustworthy
contractor to do the job for her.

Just to add a point - the router will report the current IP address of its
internet connection, which Daughter can read and report back. Provided
Daughter has configured all the other parameters required for remote
management ColinK can connect using the current address, then set up DDNS so
the router will automatically report its current IP whenever it changes.

If you want to access the config mode from the WAN (from the internet
side of the router) then you need to use

http://192.168.1.1:8080

If you want to access the config mode from the local port (i.e. from
the wireless access point, or via any of the four ethernet sockets)
then you use

http://192.168.1.1

The default login/pwd is admin/admin in both cases.

Personally I would go into Administration and DISABLE remote
management.

Having the port open is just an invitation to all the automated
sniffers out on the net to run dictionary attacks against it; my www
server logs show constant activity of this type.

(incidentally, with a Draytek 2600/2900 router, remote management via
port 443 is always enabled even if you disable it; it's a very old
bug. You have to set up forwarding to send port 443 packets to an
unused IP to work around it, otherwise the router will respond on port
443 and all the packet sniffers out there will be hitting it
constantly)
