New Startech Outdoor Wireless Access Point went from almost 200 ft coverage to less than 40 ft in the span of a week.

I work on a small ~300 square campus with 3 buildings. The internet and network we have is kind of garbage and has been for awhile. Recently I've been given the urgent task of making out network reach our most popular building so rentees can access the internet for presentations. First, we tried using multiple routers to bridge this ~200 or so foot distance, and that resulted in the wi-fi just being abysmal for everyone involved, and only covering half the building.

This was less than ideal so we decided to invest in a Startech Wireless Access Point. This was able to cover (barely) the 200 feet we needed and provide us with usable service.

Flash forward a week from installation and now the antenna barely covers more than one of the routers we used and we don't know why. We were hoping to use an extra router to extend the range a little bit further into the building but now that's a no go because the radius of the access point is significantly reduced. We've tried everything, and don't know what to do. Any help would be appreciated.

Here's a list of the equipment used in the network/ number of devices usually connected to said network:


  • 2 Netgear routers (One to be used as a base off the main modem and the other to act as a bridge between our main printer/scanner.)

    1 Startech Outdoor Wireless Access Point

    Modem is AT&T U-Verse Arris NVG 299

    1 Buffalo WHR-G54S with DD-WRT firmware and 3rd party antenna (once used as the main router, swapped out with netgear because Netgears don't like talking with Buffalo's when bridging, and we needed the printer connected. Antenna easily covers almost twice what the access point is at the moment. Was previously used in our first attempt to increase the Wi-Fi's ranged by having it installed in our intermediary building and acting as a bridged access point.)

    At any given time, the network has between 3-6 devices using the network, can be upwards of 10+ if we're renting out our facilities.

Needless to say, We have a bit of a mess over here, so any help is appreciated. Hopefully we can figure out what's going on.

Also here's a bare bones map of our network/problem, not sure if this helps, and I'm probably leaving out a bunch of useful details, but this helps, I'll leave it here.

Power Cycle doesn't do anything. Same signal throughout. Closest thing web interface has to displaying POE voltage is the option to control Wi-Fi coverage by allocating a certain amount of power to the antenna. That option is currently set to 100%. Will try the other options and see if there are any improvements.

Also recently found that the business we rent out part of the office building to installed a new internet connection using the same ISP we use. Could that interfere with something like this?

Edit: Trying lower power output settings for antenna coverage, only makes the signal worse, so I don't think it's an issue with POE providing enough power.
