Solved How to setup internet for different but close building

October 7, 2017 at 19:03:43
Specs: Windows 10
We have three separate but close houses and one internet plan with a modem and a router, we have access points in all three houses and Ethernet cables extending there. However, the internet (wired and wireless) is absolutely slow and it seems like it is barely working. Why is possible reasons are there that could possibly make it happen?

What is the best way to cover three different houses that have the same internet (1 modem and 1 router) with access points and Ethernet cables going into each building. What are the best settings that I must put the router and modem at to get the best of the two.

"Quality to you Ethernet cables? (should be cat 6, shielded, in my opinion)

With regard to segment length and bandwidth capabilities there is no difference between the STP and UTP so recommending using STP is moot.

STP is really only required in special cases or situations where you may experience a lot of interference. I've been working in IT for over 20 years and specialized in enterprise level networking for the last 12 and I've never once had to use STP.

Cat5e or Cat6 is perfect for most general usage. However..........when spanning longer distances with cables exposed to the elements (ie: outdoors) or any exterior cabling in general (ie: including in a conduit underground) you should be using an outdoor grade cable, not plenum grade. Outdoor cable has a heavier, thicker casing and is filled with grease to help prevent corrosion and degradation due to sun, wind, snow or rain.


The issue here, as I see it, is most likely the length of cables between the houses. It's been my experience that when you exceed 85% of the recommended segment length of copper, you can begin to get attenuation and your bandwidth can be adversely affected. This is especially true in the case of poorly made cables. I have to wonder if these cables were made by a professional or prefabricated? (Yep, that's one question I would like to see an answer to)

Get the cables tested and find out the exact length. If they are at 85m or above, then that's likely to be your biggest issue here. From what I'm reading above, the internet (and LAN) is fine within the house it comes into but it's the other houses that are having problems.

Is this correct?

I would highly recommend you get a tester, a real one not the kind with blinking lights, that tells you the cable length and test all cables between houses. If any are over my recommended 85%, then you can expect issues.

trvlr has asked some very pertinent questions. Please answer them. Especially the first one regard physical layout. If instead of a hub/spoke type configuration you have one house daisy chained to the next to the next, that's going to be an issue as well (that's why he asked I'm sure) Especially if the segment between the point of origin and the next hop is at or above 85% of recommended segment length. If it is, and it's experiencing attenuation, then any hops after it will be affected adversely.

So, layout and length of cables and we can go from there.

Is the internet OK if you connect PC directly to the modem? If OK;
Is it OK if you connect directly to the router? If OK;

How long are your Ethernet cables?
Quality to you Ethernet cables? (should be cat 6, shielded, in my opinion)
If you only connect 1 access point, any improvement?

How many users at the time are connected?
Your subscription speed?

I suspect problems with Ethernet cables too long (low LAN speed or packet loss)
Or a configuration problem.

Yes, the internet is OK if I connect the PC directly to the modem, we get the speed we are paying for (100 mbps).
Connecting to the router, gives a good speed usually around 50% of the speed we are paying for.

I would say the Ethernet cables connecting two houses together are long, other inside the house are average.

I didn't test connecting one access point.

About 50 users at a time (when we first got the internet, the number of people connected wasn't an issue).

What configuration settings do you recommend?

How is the network configured? The main house has the modem & router (wireless?) with an ethernet cable running to a router (wireless?) in house 2 & then another ethernet cable runs to a router (wireless?) in house 3. Are the cables less than 300 ft? Does the main router configure the IP addresses? Do all 3 routers use the same network ID & password? Are all routers the same spec - gigabit ethernet ports & same wireless standard?

There is only one modem and one router in one house. Ethernet cables run to the other houses to access points and switches. So the main house has the modem and router, the other houses have access points and switches.

Probably more than 300 ft.

There is only one router and one modem.

Thanks

"About 50 users at a time (when we first got the internet, the number of people connected wasn't an issue)."

You mean without the access points?

No I mean that we have had the same number of users, the internet was a lot faster when we first upgraded the speed, but now a few weeks after the upgrade, it is a lot slower even though we have the same number of users.

So to clarify the physical layout...

One router with three cables attached; each going to a separate house... and then into switch and then wifi access point? Makes/models of installed switches, access points may be useful to know.

Are all users on wifi only - none on ethernet!; and what access control have you setup? Access control meaning ensuring only those devices in a given list are allowed to access wifi - aka mac filtering?

Maximum run/length for cat5 ethernet cable is 100metres, cat6 may allow a little more, but nonetheless over the basic 100 is pushing it and errors will occur.

More than 5 breaks (joints/connections) on a run will sigficantly reduce that physical lengths true capacity; think of "insertion loss" . Memory is that once you to start to have breaks (as just above) in a run, you quickly reduce its efective or equivalent length to something between 40-60% of the orignal single run...; and thus the losses and errors will occur.

Quality of connectors is a serious factor as well. Cheapie kit often ok for short run domestic etc. but in the situation you describe, use better quality, higher specs...

Other factors involved are discussed here

Note the caveats re' how and where ethernet cables lie with respect to othe cables...
