BTW, this is my 1,000th post!!!!
Unfortunately, a lot of them were unnecessary.
Yeah Gil unfortunately your 1000 posts don't mean much because they were made for quantity, not quality. In fact, you may end up back under 1000 because I have been pruning some of the larger threads all day today, and admittedly most of what I've pruned belongs to you-because much of what you have posted are one word posts or otherwise unneeded posts.
Stephen, DO NOT replace the filter. You do not use a filter on the modem. I assume that you have a splitter on your phone jack so that you can hook up both the telephone and the modem. Put a filter on the telephone line, but do not put one on the modem line. I can't believe that your ISP wouldn't tell you that. The filter is interfering with the modem.
