Adding detached garage to home network

Hello all...

I am wanting to get Internet in my detached garage. It is about 25 ft from my house. I am going to place a Hikvision 3mp bullet cam on it. The camera is POE only.

I have a netgear WNDR3700V4 router in the room closest to the garage. In the garage I have a netgear WN2000RPT WIFI extender.

I plugged a 4 port POE switch into the extender. From it is went to the camera.

My problem is the connection is to slow for a smooth picture from the camera. I know each time a switch is added it cuts the bandwidth. The setup I have has 2 switches (the extender and the poe switch) in it.

I need suggestions to speed things up.

New router?
Aerial cat5e to garage?
???

Thanks for the help...
 
I'd try to get the wireless over to 5ghz if you don't want to run cable.

I don't know who told you adding a switch cuts into the bandwidth but that's some of the dumbest stuff I've heard in a while. The bottleneck in your situation is probably the point-to-point wireless connection and it's probably not bandwidth but interference on 2.4 that's the problem.

To rule out other things as the issue, move the PoE switch and plug it into your router and temporarily move the camera and plug it into the PoE switch and see if it's working any better
 
Each time you put a switch in are you not dividing the bandwidth by the number of ports on the switch? Say you have a 100mb coming into the switch. It is a 4 port switch. Each port would not be able to get the full 100mb. If you added another 4 port switch the bandwidth would be divided again wouldn't it?


And I will move the poe switch to the router and bypass the WiFi extender. See if that helps.
 
Use Ubiquiti bridges. Nanobridge 5Ghz units (about 70$ each) will work perfectly. Make note they are 24V PoE, not 48V, so don't try to use your PoE switch. I use them between in laws house and their barn where they have several computers and cameras for their car restoration business. Plenty of bandwidth, and easy distance for 5Ghz to do in all weather.

Each port would not be able to get the same 100mbps at the same time. Each port would still be capable of 100mpbs though, so if you have one upstream port and one downstream port it won't have any real effect on the bandwidth.
 
How is the wifi extender linked to main router? You may want to use 2.4ghz and set the ssid to be different from 5ghz and make it 802.11n only.
 
Found something out. This extender does not do 5ghz. And I can find no way to force it to stay on N. When I checked the speed it was running at 39Mbps. Then a bit later went to 78Mbps

Ok. So the bandwidth only divided by the number of active ports. That makes sense.

no still not correct. The bandwidth is shared. For example; If one active port only uses a little bandwidth, then the other active port gets almost full bandwidth.
 
Since is a repeater, you are halving the bandwidth because the repeater spends half its time receiving the signal from the client, and then the other half retransmitting it back to the router.

If you have 39Mbps speeds, figure you'll lose roughly half of that due to wireless overhead, especially since it is a fairly low data rate. So you are talking about 18Mbps. Now halve it again, because of the retransmission penalty of the repeater.

Figure 9Mbps max and probably a little slower, especially if you have other wireless activity going on.

Get an inexpensive wireless bridge and point it back to your router and bridge the connection then. Much higher gain, so you'll get higher data rates and no worries about repeating penalties.

Honestly at 25ft, I'd just hop on my computer and order 100ft of direct bury Ethernet and run the connection hardwired out to the garage.

Is no place to set n on the router.

If it wasn't concrete between house and garage I would already have a piece of conduit in the ground...

Just looked at the manual and it does look like the mode setting doesn't have n only. Bizarre.


get a wireless bridge that supports 5GHz. or get a better wireless router and turn the netgear into wireless bridge. flash dd-wrt onto the netgear.

Yep. That what I thought. Maybe time to upgrade router. Good excuse to give the wife that we need a nighthawk. ...

I think I am gonna look into a point to point or point to multi point bridge. That way I have a strong dedicated signal

tell her this is the alternative 😛

I have one of those in the garage from my old house. I was helping a guy test wireless internet. That was 15-20 years ago....
