Hi, i have been using 802.11b for about 6 months everything work fine (although i need to keep changing the frequency every month because of interference). Recently very weird problem happens to my neighbourhood. I scan using snooper tools on mikrotik to find the usage of each channel on my environment, i found out that channel 2-8 has no AP on it. So i decided to change my AP (omni antenna) using any those channel, but the result is my client couldn’t associate with my AP, no matter how many times i restarted the AP or the client, the results is the same. THe distance between my client and AP is 1 km (LOS). Does anyone know what is the cause of this weird problem? Please some wireless guru help me with this. Because channel besides 2-8 is very crowded in my area, so i am thinking of switching to those channel.
I have got another question, does 802.11a would be really free from interference? I wish to try this but i need to suggestion about it first. Thank you everyone.
