1 edit | Connection Very Unstable I have a wireless ISP and I have noticed that my speeds have a tendency to fluctuate greatly and I have extreme lag to my first ISP subnet hop. If I try and download something from an FTP server one time it may download at 300K, and if I stop it and start it again the next time I start it a few seconds later it may start out at 15K, stall out and drop to 5 or 6K. Sometimes it is so bad I cannot maintain a 32Kbit radio stream with nothing else going through the line. It seems like when I run bit torrent and it only runs at 30K it slows the entire connection down so if you try to load a page or run a stream it will not connect to the server. Sometimes bit torrent slows down to 5 or 6K and the entire line stalls out. A month ago and before I've seen bit torrent easily go over 200K. The ping times are sometimes over 1000ms to the access point. It appears that there is a line of site to the tower, but there is a tree right below the tower from where the antenna is. Does this sound like an antenna issue? I want to have a good idea as to what is going on before I contact my ISP because ISP tech support in my case is a pain. Thanks. | |

| Re: Connection Very Unstable Either you have line of sight or you don't. Which is it? LOS is a straight line between the AP and your CPE plus a margin called the fresnel zone. Depending on distance, this fresnel zone could be 25 or more feet on either side. Generally, 60% of the fresnel zone should be clear.
Usually, the AP is not a router per se, so users cannot normally calculate ping times to it directly but none the less the first router you encounter in a tracert should be what you base your last mile performance on. Keep in mind that routers often put a low priority on ping, so if something further out gives you better times, you can discount the bad times.
Just do your homework with a few tracert and pathping results and confront the WISP with them. That should get things moving in a positive direction. Just make sure that you are not causing your own interference with your own DSL router or new cordless phone. | |

| The results from the traceroute only result in a 90ms lag, but this still doesn't solve the problem of the reliability and slow speed. I have access to the signal strength, bit rate, link quality, noise level, etc... Signal Strength: 25%, Link Quality: 29/255, Noise Level: 0/0, Bit Rate: 2mb/s. The bitrate of course fluctuates somewhat, but it is usually stable at 11mb/s when there isn't a lot of traffic. It hasn't been staying at 11mb/s when idle like it normally does. I have also noticed that the signal strength has dropped from what it usually is. It is normally 32-33%, but now never goes that high. I hope these results can help. The bitrate is especially low when running bit torrent, sometimes as low as 1mb/s. | |

you will never get "full speeds" using bit torent. | |
