Antenna Positioning
« on: February 22, 2016, 06:42:59 PM »

 ??? ??? ??? ??? Having issues with getting strong signal in one important room in my house... my office. Would really help if I knew how the antenna positioning  worked. (Vertical, 45, Horizontal??) Have a wifi analyzer installed so I know hat to look for. Just looking for some advice.

Another question is do all the antennas send out N, AC, AC 2 or do the front two work as one , the middle as another, and the back as another. My back antennas just stick straight up. Thanks for the help

Found something here  ;D

Links>Wireless Installation Considerations


Antenna Orientation

The D-Link DIR-890L is designed to give you the fastest, most stable network connection possible. In order to maximize performance, orient the antennas at an angle, pointing outward and away from the base unit.

Link>Welcome!
Look at the links provided. General rule though, if your in a single level building, point antennae vertical UP and Down. Multi level building, point at an angle.

Is SmartConnect enabled?
What is the measurement in SqFt of your house>?
Router Placement
Forum User - "Well I feel really dumb. After moving the router away from other electronic devices my speeds are back to normal. Just a heads up for anyone experiencing slow speeds, you might want to move it away from other electronics and see if that helps."
3-6' feet minimum safe distance between devices.
Placement on main level floor and central in the building and WELL ventilated is preferred. Not in basements or closets as building materials, or near by electronics devices could interfere or hinder good signal propagation.

Smart Connect enabled. 2600 sq feet two story. When the antennas are all vertical the 2.4 Signal is 51, 5 Ghz A 57 5 Ghz B 59 on the side of the house I am having issues. I have 100MB/100MB fiber connection and speeds on that side of the house drop to 30/15 and are not stable. With antennas 45 degree angles signal strength get worse but seems like speeds increase to 75 MB download/ 45MB-94MB upload. Does the direction of the antenna's flat side matter? I see they rotate. Thanks

2.4ghz is supposed to travel further than 5ghz.

Is the router location on the opposite side of the floor of the house?

Take your divide and stand in front of your office wall and measure there to see how much drop off a wall has.

And were you successful using any device before?

You'd  be more successful running a gigabit wire to toe office, or at least somewhere closer to the office.

Placement of the router can be crucial as well. I have a 5000sq ft house and get signal good all over however at far ends of the house is a bit less as I have my 890L on the upper level 2nd story since we mostly populate that side of the building now. Like RYAT explained 2.4ghz will travel better thru walls and building materials better than 5Ghz. 5Ghz is effected by its high frequency so it's best in there line of sight or one wooden all away at about 20 feet approx. Also be aware that wireless testing is not preferred due to many factors that contribute to bad testing and results. Wired speed testing is preferred.

Usually angling the antennas should provide best operation for multiple story building as the single gets propagated at a wider range than up and down depending on placemetn. Central on the 1st floor is recommended. Test out on the 2nd floor as well depending on you population of the building is most of the time.

The is mainly only getting you additional speed on connection rates which still some client side HW is not fully supporting as of yet.

Yes router is in the opposite side of the house.. I raised it but that really didnt help.  I can't wire into my office becasue of the cable looking awful  ;D ;D Wife wasnt having that. My ISP said they could wire my fiber to the my office outside for another $300... Before I bought two of the new apple airport extremes and had one downstairs and one in my office. Worked ok 75% of the time but the routers wouldnt hand off the signal so sometimes I would be upstairs using downstairs router. It was a mess. So i got the 890. Now my question is should I get the 895? Will it provide greater distance? the 6 reviews I have found sound good, but zero professional reviews

Upsatirs. Back Right Corner Office


Down Stairs


Thanks again

Wow, thats pretty good for having the router at one end.

Any chance someone in your area does cabling installations? I know if I was there, we'd be up in the rafter running CAT6A. I can be done after the fact too and would look good. I used this in my existing house that was old for running cabling:
http://forums.dlink.com/index.php?topic=52726.msg202260#msg202260

As for getting another, review this first for your considerations:
http://www.smallnetbuilder.com/wireless/wireless-features/32238-ac1900-innovation-or-3d-wi-fi

For the size if your house for your current configuration, I don't think you'd benefit greatly by spending that kind of money on a 895 if your going to use it as a wired AP. If you could move the 890L to a more central location.  ::) You might do better by installing either a wireless bridge and use it as a wireless/wired connect to your office PC(s) or maybe a extender however I prefer bridges has they have better performances and are less ****e to cause interferences.
Would look something like this:
Suggested N or AC WiFi Bridge Upgrade
This represents getting wireless signal using a bridge to a game console however works for PCs and other wired devices.

Yes you can use another wired AP however you have to get the wire from the 890L to the 895 if you did this.  ::)

Thanks for all the help. What do you think about power lines? Especially this one.

Yes those could be a solution too. I haven't had any experience with the D-Link ones. I presume they should work well. There maybe some or little performance loss due to the traversal from LAN to PL conversion I would presume however should be very minimal or not even detected.

PLs can be effected by noised on the power lines.

OK last question is about 895... I would sale my 890 online and then grab the 895L...

1) is the new broadcom 1.4 going to make difference is handling my devices (usually 20-25 connected)

2) Will the 8 antennas help with range?

Only reviews I can find








Glad this board exist. Learning a lot in all the post

400Mhz can be of some help however I presume some of that is doing the wireless handling of the 1000mb on 2.4Ghz and 2166Mbx2 on 5Ghz.

My 890L has been handling my 20+ devices just fine.

Antennas are probably for the additional wireless speeds and MIMO features in the wireless. I believe the actual output signal power is the same for the 890L.

The one review is in regards to the 885L...  ::)
