I have a LAN between my house and my neighboor's; we're using patch uni-directional antennas to send the signal, with switches on each side hooked up to other computers. When we first set it all up, the data transfer speeds were great, so we hard-mounted the equipment. However, as of late, the quality of the connection has deteriorated substantially on my download speed. My download speed is horrendous. For some reason, the upload speed remains the same. Does anyone know what would cause this discrepancy? I can provide more information if necessary, but let me know what details would be useful.
