Hi  @rehashed 

Since you already try multiple wireless optimization, you may refer to the following solutions:

• Upgrading to Newer EAP Models: Upgrading to a more recent EAP model like the EAP650 with its advertised "long - range coverage" could potentially help. These newer models may have better antenna designs, more advanced radio chipsets, and improved signal - processing algorithms that can enhance the range and stability of the connection. However, it's important to note that even with a new model, the antenna characteristics and the need for a proper line - of - sight still play a crucial role. EAP650-outdoor is a good choise.
• Bridges: Using wireless bridges instead of relying solely on the mesh functionality could be another option. Wireless bridges are designed specifically for point - to - point connections and can provide a more stable and higher - speed link between two locations. They usually have more advanced features for optimizing the connection between two specific endpoints, such as better signal amplification and noise reduction capabilities. For TP-Link wireless bridge products, I would like to recommend EAP215-Bridge KIT.

  @Vincent-TP Thanks for your reply, however I was hoping for a bit more tangible information than just "you can try these two options that are the same as what you suggested" as the outlay for each is in the order of hundreds of dollars.

The EAP225-OUTDOOR, which i already have also says "long-range coverage" in the marketing material, and clearly 30m is "too long", so is the newer EAP650-outdoor going to use the same definition of long, or is there any tangible info about how much further, given that it doesn't use a directional antenna? It seems like it should provide vastly increased performance over the equivalent bridge if it can use a 160Mhz wide backhaul?

What is the expected performance out of the EAP215 bridge? I know that you list 867Mbps on the marketing material, but from my experience of bringing the APs close enough together that they negotiate at 866 up and down, i only get measured half duplex performance point-to-point via iperf at 140Mbps or so, so is this going to be the same case for a bridge? Shouldn't i be able to achieve exactly the same performance out of the EAP225-outdoor with a directional antenna (the EAP255-outdoor is advertised as having interchangeable antenna, so clearly thats considered an option) without having to purchase more hardware with the same basic spec?

Hi  @rehashed 

I understand your concerns about wanting more specific and tangible information before making a significant investment.

However, wireless performance is highly susceptible to the wireless environment. This is especially the case with your outdoor mesh setup. We are unable to provide you with specific recommendations because we don't have the same understanding of the local wireless environment as you do. The suggestions we gave before were based on our experience. If you are not confident about it, you can purchase a set from a store that allows returns and test it first. If the performance doesn't meet your satisfaction, you can return it.

Replacing the antenna of the EAP225- outdoor units is also an option. We don't sell antenna any more, so I didn't mention that.

What's more, we don't guarantee the compatibility of third-party antennas.

You may have a look on this article in case you want to change the antenna:
