    Lessons Learned from Antenna Experiments

    This is totally off topic but... Those are actually some really nice building exteriors. A little paint would do wonders... You have to be a little crazy anyway to want to own old buildings. An axe murderer or psycho chainsaw killer just adds a little charm. :D...

    Lessons Learned from Antenna Experiments

    Christine, Those are very valid questions. I offer a common WiFi connection as a low cost alternative to the tenants purchasing their own bandwidth from either a Cable or DSL ISP provider. The service I have is the highest bandwidth offered by the local DSL provider (40Mbps download...

    Lessons Learned from Antenna Experiments

    I don't have a Netgear R7000 router so I cannot give you an absolutely definitive answer about that. Based on your circumstances of how much vertical coverage you need to achieve and the type and quantity of obstructions, one might be better than the other -or not. Try them both and find out...

    Lessons Learned from Antenna Experiments

    The 2.4GHz antennas definitely will not "destroy" an RT-N66U router. I know this for a fact because I owned one and did a lot of testing of antennas with it before I sold it to a client. The RT-N66U router has the same benefits to the signal quality as the RT-AC66R routers that I tested...

    Lessons Learned from Antenna Experiments

    Stevech, Thanks for the input. I did say in my posts that the changes I made were often subtle, but measurable. Because I did not use purpose built test equipment, I was often not able to effectively capture the actual gains seen by the clients in terms of the quality of their wireless...

    Lessons Learned from Antenna Experiments

    I have a couple multi-family dwellings (apartments to those of you who are not in that business). I live in one of the units. My goal in doing these tests was to try to get the best signal quality I could to the tenants on all three floors from the minimum number of wireless repeaters or AP's...

    Lessons Learned from Antenna Experiments

    With stock antennas, I didn't see a lot of interference between them when I had them vertically oriented. When I started using the 38cm antennas is when I started seeing a reduction in signal strength. Especially on the 5GHz frequency band. Again, radio people will say "DUH" since they...

    l l / ___ A very crude representation of the antenna configuration. If I remember, I'll post a picture when I'm able.

    Lessons Learned from Antenna Experiments

    To do my testing, I kept the "stock" router antennas as a constant to test the effect of changing the transmitter antennas. When I got into doing download/upload transmission rates I did a few of the "best" antenna configurations on both the sending and receiving routers. That was to...

    Lessons Learned from Antenna Experiments

    For those of you out there who will ask "Why not try something other than a omni-directional antenna"; here are a few others that I tried. Flat plate type http://www.l-com.com/wireless-antenna-51-ghz-to-58-ghz-18-dbi-panel-enclosure-antenna-with-rp-sma-plug-pigtail-cable I thought this was...

    Lessons Learned from Antenna Experiments

    Thanks for posting the website link. Someone on a ham radio site recommended it to me. I didn't expect my post to be a sticky or to be referenced when I wrote it so I didn't include any charts or links. I did purchase a 5.4GHz omni-directional antenna (among others) to test. Here's the...

    Asuswrt-Merlin 376.47 Beta 1 is out

    Does 376.XX have Power Limiting? RMerlin, In a previous post of a different thread made a comment something like (I am paraphrasing from memory here) "All FW revisions from 376.XX on will have the kernel which will not allow changing the country codes and will have the input power restrictions...

    Lessons Learned from Antenna Experiments

    I have to say that much of my router antenna testing was prompted and inspired by THiggins articles which tested different wireless radios on different routers. Thank you Mr. Higgins. I attempted to see if I could introduce some of the same scientific approach and rigour to antenna...

    Lessons Learned from Antenna Experiments

    [Ed. Note: Moved to its own thread to increase visibility] I spent several months researching and trying different antenna configurations for my RT-AC66 routers. I went to radio sites and posted on their antenna design sections. I bugged people on this site till they were sick of me. The...

    updating new firmware from old version

    Use the 374.43 Fork instead of Merlins 374.45 Build Any version of F.W. done by Asus or Asus-Merlin after the 374.43_2 build will have the new FCC restrictions on Wireless Radio Output Power. This can significantly curtail your routers power output and apparent signal strength by your wireless...

    [Fork] Asuswrt-Merlin 374.43 LTS releases (Archive)

    Is there any Visual Change from the Asus-Merlin Std 374.43 FW? I installed the v.3 Fork Update for the 374.43 Asus-Merlin F.W. on a couple of Asus RT-AC66 routers yesterday. The install was smooth and the reboot worked fine. I did some tests of power output and basic stuff to ensure that...

    Asuswrt-Merlin 376.45 is out

    Ver 376.44 & 376.45 Channel Defaults to 36 I have 2 - Asus RT-AC66's which are running .43 Asus-Merlin firmware. I installed .45 firmware on both routers and did a complete reboot and nvram purge. Because of the change to the power settings I was evaluating the routers signals and found...

    Asus-Merlin FW vs Tomato or DD-WRT for RT-AC66 or RTAC68 Routers

    KGB7, I'm not sure if you are agreeing or disagreeing with my statements that disagreed with your post. No, I do not believe that firmware can make hardware perform beyond its fundamental design capacity. I believe that the previous post which I quoted (by you, I believe) stated that the...

    Asus-Merlin FW vs Tomato or DD-WRT for RT-AC66 or RTAC68 Routers

    I have a Buffalo WZR-1750DHP with the latest stock firmware. I abhor the stock firmware and would like to upgrade to something better. Can you provide a website link where I can get the DD-WRT-Brainslayer firmware for the Buffalo router? Also instructions on how to install it? (My apologies...

    Radio Connections to Antennas on RT-AC66 Router

    I believe that I can visualize what you are saying regarding the field interactions of antenna being distorted by the other antenna fields. It is easy to visualize the distortions of the field when the 3 antennas are parallel to each other. That causes the center antenna field to be pushed out...
