Question will 2 squid proxi servers help to speed up my connection?


I installed an wireless connection between home and my office (6 Km) and and I was hopping it will work at 11 mbps but its working at only 1 mbps. Since I also installed squid as a proxy server in my office I thought that by adding a second squid server at home, this second proxy will take care to “accumulate” at high speed the data requested to the internet pages by users in my office, and then from there back to my office slowly but efficiently. Now my problem is that when users request ftp downloads, or trying to chat with friends on the internet, the connection dies and the people at my office fall to sleep waiting for answers that never arrive. This also happen some times with the downloads of our e-mails from gmail etc. Of course that I am not an professional IT hacker, but I started almost a year with linux and I got this far. Any comments or suggestions?.- Will it be worthed to spend time doing this?. the wireless connection is at 2.4 wireless.

You're sharing your home internet connection out to the office over the wireless link? If yes, I can't see how a second Squid would help. Have you tried to improve the wireless link with higher gain antennas, better antenna placement, lower loss cable? At only 1 Mbit (the slowest B/G adaptive rate) I expect your wireless link is marginal with poor SNR and may be suffering from packet loss. Also look at traffic shaping to prevent bulk traffic like FTP from swamping the link.

Ok I will not try to set up 2 squid servers. I am in the border of a desert and there are winds with sand, and near the sea with lots of salty fog. I am using 24db gain parabolical antennas at each end (access point and client sides). There is a lot of radio interference. I will try to improve the transmission settings of the AP and client. I may need new equipment outside the 2.4 range, perhaps it will be better. Thanks again. Any suggestion for a long range wifi ap etc?

I had a 802.11b link running over an 11km path a few years ago as part of a community wifi experiment. It was not entirely reliable but it worked pretty well most of the time. Something killed the other end of the link before I got a chance to upgrade my 15db antenna to a 24db and compare results (the guys at the other end never got back to me about the problem). I'll dig out my logs later and see what link speed, signal and SNR were on that link.

Directional antennas should minimise radio interference except in the direction they're pointed (mine showed a much lower noise level and better gain than an omni I had up).

Have you tried other channels?

Have you tried other 2.4GHz radio hardware?

Do you have clear line-of-sight?

Are the antennas on stable mounts? (They'll have quite a narrow beamwidth so any wind-induced movement could affect the link).
