Some WISP questions
I have a couple of questions that maybe someone here with some experience could assist me with.
The WISP I'm a customer with has me hooked up to a tower that's around 7-8 miles away. The technician that has came out here for basic maintenance work has assured me that I have a good signal, and that he can clearly see the tower from my location. My house is elevated quite high on a hill and can see pretty well in all directions. The radio I have been issued is a Nanobridge M5 at 5ghz. The speed I'm paying for is 3/1.5
The performance issues I experience on a daily basis are as follows. Extremely slow download speed, non existent upload speed, very unstable ping times and high amounts of packet loss. This generally always occurs in the same time frame. Late afternoon all the way to the late evening hours and even sometimes early morning hours. I'm guessing peak hours are the culprit. Every other time of day it's usually pretty stable.
Now the questions I have. Is my distance from the tower playing a role in any of these issues? Would me being any closer to the AP lessen these problems? I have spoken with one tech that has told me my distance is a problem, but the field tech (who appears to be more educated) that has been on my property seemed to think everything looks fine and dandy.
I apologize for this wall of text, but it's extremely difficult for me to get any answers out of these guys. I try to be as polite as possible and never overreact when I do speak with them, but I don't want to be a burden calling every day and night trying to get something fixed that may not be fixable.
I doubt the distance is the issue.
I am more than 10 miles away from my WISP's tower (running 5Ghz) and when they open the pipe (turn off any throttling) I can see 10M/sec down.
While they were having hardware issues and were working on router rules and throttling I was seeing 600k/sec down and 1.5M up but a week or so ago they got their ducks in a row and I'm averaging 2-4M/sec down and 1M up.
I run pingplotter on a VM and have it set to send out ICMP packets every 15 seconds. I still see the occasional drop of an ICMP but it is 1 an hour or so which is fine by me. My VPN + file transfers handle it just fine. When the network was having issues I had lots of dropped packets in my log and would see connection resets while trying to do file transfers.
To watch the speed I use PRTG (an older version) which will query via snmp. I have it watching the link between my router and the CPE which means it includes overhead.
If I use speedtest pages I can get wildly different results depending on the test I use. Speedtest.net usually gives me better results than the Java based or even the flash based one's listed on DSLReports so I don't normally use them.
In case it matters, my CPE is 15 feet in the air on a antenna mast made from black gas pipe that is in the ground 18" or so and also attached to the fascia boards of the house. It does wiggle but even in the high winds it doesn't move much, even with 2 other antennas on the mast.
My guess is your ISP has either oversold the bandwidth they have, has routing/hardware issues or is running into interference from something.
I'm surprised my ISP isn't running into interference issues since my 'net connection goes through 3 wireless hops before I hit a hard line and it shoots across the city.

said by Soupsopsup:5 GHz is just a generalization. There are different EIRP limits and radar avoidance within that band, so with that limited info, one cannot say for certain that distance is not the issue.
The radio I have been issued is a Nanobridge M5 at 5ghz.
Ask your WISP what your RSSI levels are for both ends of the link.

I would recommend finding out how that tower is connected to the rest of their network. If you do have clear LOS to the tower, it is likely that the problems you are experiencing are upstream from your Subscriber Module and Access Point. If the tower is fed via Wireless BackHaul, find out what type and how much throughput it has. If the tower is fed via Fiber, cable, etc, find out how much aggregate capacity is supposed to be available. WISP service can be extremely reliable and fast when it is engineered properly. You also might ask the field tech was CCQ% is for your connection, although its not likely the cause, it can indicate the quality of your wireless link. Hope this helps.
