Building to building wireless

[pohorsky]

At work, the internet situation in one of the buildings was brought to my attention. Satellite internet comes in one building and goes into a Nighthawk. Cable goes out into a wired network switch which distributes the internet via cat 5. One building has the cable underground and internet speed seems fine. Another building has cat5 on the ground with maybe a max length of 175', probably closer to 125'. Slow internet in that building. Both secondary buildings use the same model of router and probably have around the same distance.
Several questions.
Is there any reason to have the network switch immediately after the wireless router?
What could be causing the slow internet in the one building?
Ethernet cable on the ground is not a good long term solution. I thought about maybe switching the cable out for something like a nanobeam. Good idea or is there something else I should be looking at?

Not enough info.
Dont know how many legs.
Dont know how many devices on each leg.

Keep switch cascading to a minimum. If you do cascade, you are aggregating everyone through a single port. That aggregated point will have equal contention to a single host on the upstream switch.

I'm not sure I understand all the terms, but I'll try to explain.
A is input
B is location with good speed
C is location that is slow
No location has consistant use.
internet comes in A and provides wireless service to one building, no wired connection. There are sufficient ports on the wireless router, but only one output is used. Several ports are used on the switch.
Cables bring internet to buildings B and C.
Internet comes into building B and into another switch with 3 outputs into wireless router and two computers with minimal use.
Internet comes into building C and connects to wireless router and provides wireless internet for the building. No wired users. Doesn't sound like a traffic issue, as it appears to be a constant problem, independent to the use.

Do a cable test on the long cat 5 cable connecting the building with slow internet, most likely than not, that cable isn’t working correctly or is damaged.

Whats the programming look like? What kind of switches are those? They might also be acting as gateways. Thats how I've always done that with segmented networks. In a situation like that I would segment each building into its own subnet (VLAN). Could be a cabling issue, could be a programming issue. When linking up buildings I always use fiber and pull 6 strands minimum. If you have access to an analyzer you could test each one of those runs.

Building to building wireless

The only testing tool I have is a Klein vdc scout pro 1, which unfortunately is in storage right now. I can probably grab it this weekend. Switches are rosewill rc-416. I don't know what programing there is if any. Seems more My experience is strickly on the hardware side. Nothing is linked up as far as I can tell. Each building has its own wireless network with its own password.
Aside from main wireless router, the other routers are tp link tl-wa801nd.

Yikes thats all home consumer type stuff. Other than your core router I don't think any of it is programmable. Just normal layer 2 switches. It could be a bad port on that switch. Have you tried a different port? That would be a really quick thing to do. Otherwise I would get a cable tester on there and just make sure that cable is adequate. Home Depot and Lowes have those cheap simple testers. You could pick up a crimper and ends too if you want to put new ends on the cable. Does the cable run next to any power lines or anything? Ethernet is supposed to run perpendicular and not parallel to power (but in reality I've done it and had no issues... its all properly grounded). I think I have that same tester as well somewhere. It has a remote dongle which is what you need. I don't recall if it does length and impedance and all that. I have an ancient Black Box tester that does.

It sounds like your internet comes into the core router, that goes to a switch which is split between 3 buildings and each one has its own access point. Thats not an abnormal setup or anything. Are the slow clients only on hardwired in that building or hardwired and wifi both?

[pohorsky]

Nothing is hard wired in the building just wireless. Cable runs under the building up the hill to the building behind the trees. I just discovered that the cable for whatever reason goes into a tplink poe injector and then into the wireless router.
That is why I was thinking about replacing the cable with a ptp wireless antenna. Where I was before we switched to a full ubquitity setup. If we would be miles ahead, we could switch to their wireless routers and setup. Of course our internet speed probably maxs out at 35 mbps.

[Misterclick]

You and I should talk sometime. I am local and might be able to help you out.

[the86d]

Are you getting 1Gbps netwrok link-lights links on all those ports when plugged in, or slower 100Mbps, or even 10Mbps links?

I'm with you on the point to point wireless. If the cable is just run out there it could be half eaten or weathered and have water in there, who knows. Ubiquiti is good stuff. I've also used Aruba, Meraki, etc. A trick on the antennas is if it doesn't have great signal even though aligned (use a laser alignment tool), turn the antenna 90deg and try again.

So I've be looking around the site and it turns out there are comm conduit 2". So I imagine it makes sense to scratch the antenna for a hard line. With this in mind, what cable does it make sense running, Cat 5, 6, fiber? Conduit currently has I believe one 16 conductor phone cable.
Cable would run from building to box to box to box to building. Overall length is under between 250' and 300'.

If you dont have fiber already, do cat6a. Pull multiple cables for more bandwidth and aggregate them (etherchannel/link aggregation/teaming/bonding/etc).
