Can't send email reliably

[Web]

Recently installed wireless network through the calble company. Now, I
can't send email reliably. No answers from cable company. Email
always worked before. I can receive fine.

You should give a few more details in your question if you want a detailed
answer. I can only hazard a guess on the basis of such sparse info.

Basically, with POP/SMTP clients you can retrieve email from any source, but
email must be SENT via the connection-provider's SMTP server. This is only
reasonable as the provider doesn't want unidentified people sending stuff
(most likely spam) through their equipment.

You need to:

A: find out the DNS name of the cable company's SMTP server. The website
will probably tell you this.

B: Put this into your email program's settings , in place of the previous
provider's setting. In Outlook Express you find this under
Tools>Accounts>Mail>Properties, and on the second tab, 'Servers.'

Sorry for the sparse info. I havent' changed providers, only added the
network. I was connected before (only one computer) using Comcast
cable. I am still using Comcast, but I had them add two other
computers via wireless. I didn't change any email settings. Comcast
tech support walked me through all the settings, and everything is
correct. Some emails get through, and some get through after a delay
(up to 10 hours). Some emails don't make it at all.

obvious reason for the problem. Comcast is still looking into it (they
say), but I haven't heard from them in two days. Two of the three
computers on the network have similar symptoms ( haven't tried the
third one on email). All computers can connect to the internet with no
problems.
I hope this extra info helps.

Unlikely this is anything at your end, almost certainly a problem with the
ISP's mailserver.
