I came here to begin a new thread, but maybe it's appropriate to
piggyback on this one.

No, it isn't.


I'm also having trouble connecting to the internet on my laptop. Both
browsers say "done", but I get no graphics. Thunderbird receives
mail, but doesn't send (it has the same SMPT as my desktop). I
finally got a brief popup saying there was an IP conflict. I have no
idea how to figure that out or how to rectify it. I suspect that
although I'm directly connected to the net via a router, my computer
must also be trying to access via wireless too.

Can you help me with this or should I take it to a shop and have them
figure it out?

You can disable the wireless adapter if you're connecting by wire, which
would prevent that from happening. Many laptops have a switch for this
purpose.

Releasing and renewing the IP address will force the NICs to get new IP
addresses from the router.

From a command prompt issue an "ipconfig /all" command and ensure that
wired
and wireless adapters, if both enabled, get IP addresses from the same
router.

If your router has wireless, be sure you've changed the SSID away from the
default. It's very possible for Windows to decide to attach to a different
router that has the same SSID.

No. That didn't help. I didn't understand a single direction. Can
you simplify what you said to help an "idiot"? "ipconfig/all" gave me
an error message when I entered it into "start > run". Was that what
you expected me to do?

No, go to Start, run, type CMD, and press enter. THen type "ipconfig /all", and note that there is a space before the /.

You will get an error message if you leave the space out, and if you don't do it from the command prompt, which is also (mistakenly) referred to as a "DOS window", the command will execute and vanish before you can read it.

The command "ipconfig /release" will reset all the IP address to 0.0.0.0 . You then issue the command "ipconfig /renew" and this will force the network cards to get new addresses from the router, if it can.

The SSID is the name you gave your wireless system at the time that you set up your router. When you scan for networks with the wireless card, this is what you see.

If you didn't do this, your router is using the default SSID and if you have any neighbors with computers there's a good chance that they have similar hardware and the same SSID, and Windows can easily become confused as to which one to attach to. Check your router's documentation for changing the SSID, change it, and be sure your system is connecting to the right router. This is best done with a wired connection.

Now, the fact that you can receive but can't send mail often indicates that you are connecting to the wrong network.

For example, let's say you subscribe to a DSL service and set up your mail with the information from your provider for their POP/SMTP mail servers. You know the information is right, and you can receive mail but not send it.

Major ISP's SMTP servers use port 25, you can't change this, and for security reasons (spamming) ISPs do not allow access on port 25 if you are not connected to their network. If you aren't on their network, your mail will not send, even if all the rest of the configuration is perfect.

So if your mail does not send and you are sure the settings are correct, this is a big clue that you're on the wrong network.

What often happens is that your PC has decided to connect to a neighbor's wireless router - because it has the same SSID, or you incorrectly pointed the wireless to their router - and they have, say, a cable internet subscription, with a different ISP. You're on a different network, and your ISP will not allow to you access their outgoing mail server from this other, or ANY other, network.

If you travel with a laptop, you're almost certainly going to run into this when you connect at different locations. What you have to do is find another outgoing server that isn't your ISP's and does not use Port 25, and set up your mail client to use that as the outgoing server. I often use gmail for this purpose. Then, you can send and receive from pretty much anywhere in the world there is network access.
