I have a Linksys WAG54G wireless adsl router (using 1.02.7 firmware) + WUBS54G (using version 4 drivers) operating over a distance of about 50 metres. I have tried operating on various channels, and am currently on channel 1. I use the Linksys connection utility, not Microsoft Wireless Zero configuration.
Sometimes this works well - the remote PC can connect to the Access Point and to the internet ok. At other times the remote PC can connect to the Access Point but not the internet, and sometimes it can't even see the Access Point.
My system seems to have problems when a VERY strong signal (from elsewhere) comes up on channel 6 at random intervals. The intermittent nature of the competing signal makes it look like another WLAN rather than a cordless phone, microwave oven, etc. Even when I operate over a 2 metre range the competing system can still come up stronger than my signal. I'm wondering if the competing system is radiating excessive power.
Q1). Are there limits to the allowed radiated power for these systems? Q2). Is there any way of estimating the radiated power of nearby links?
