OK, lots of stuff here... First, I NEVER use channel 5, 6, or 7. I rarely use 4 or 8 either.
Any time I find a client router on anything other than 6 I move it. MOST home routers default to channel 6, so that's a good thing to stay far far away from. You should be able to easily connect to something that's got a -80 signal. What is the signal level at the AP? Do they match what the cpe is seeing? At least close to the same? OK, next test. Can you ping the radio from the customer's computer? How does it do? Are there any components that have NOT been changed out yet? I've seen cat5 cause some strange things. If you want, put a public ip and temp pass on the ap and cpe and give me a call. I'll see if anything stand out to me. Sometimes another set of eyes makes a lot of difference. Also, have you tried rotating to a different polarity? laters, marlon ----- Original Message ----- From: "Mark McElvy" <mmce...@accubak.com> To: "WISPA General List" <wireless@wispa.org> Sent: Monday, October 19, 2009 12:20 PM Subject: Re: [WISPA] New install driving me crazy.... > So I go back out to the customer to do some testing.
