1. THE SHORT ANSWER

If you are running a dense home lab environment like mine, here is where you should put your money.

• Buy TP-Link RE300 if:
  • You need a low-profile device that can hide behind a monitor in a Proxmox cluster rack without being visible.
  • You require the ability to assign static IPs to your extension points so you can script management via Home Assistant or shell scripts.
  • You are on a tight budget and need a secondary node for a 4-node Proxmox cluster that doesn’t require enterprise-grade throughput.
• Buy Netgear EX3700 if:
  • You have a single 2.4GHz access point in the basement (my Synology NAS location) and need reliable 5GHz extension for a single floor.
  • You prefer a larger form factor that acts as a small heat sink for the electronics inside.
  • You are okay with a slightly more expensive device that offers better range but lacks the feature set of the RE300.

2. WHO SHOULD NOT BUY EITHER OF THESE

Let’s get the obvious stuff out of the way. If you fall into these categories, do not waste your time configuring these devices. They are repeaters, not routers, and they will not save you.

• Users needing full routing capabilities: If your primary router died and you need to run DHCP, VLANs, or firewall rules, neither of these devices can handle that. They are daisy-chain extenders only.
• Users expecting seamless mesh roaming: Both devices use legacy WDS/Repeater mode. If you walk from the basement to the kitchen, your connection will likely drop or switch to a weaker signal. If you want true mesh, you need a dedicated mesh system, not a repeater.
• Powerline enthusiasts expecting magic: If you plan to use a powerline adapter as your primary backhaul (as I have done in the past), you will be disappointed. The throughput drops significantly when you add a repeater to the line. I have seen speeds halve just by adding a second node to the Proxmox cluster network.

3. KEY DIFFERENCES

After eight years working as a network engineer for a managed services provider in the Pacific Northwest, I have seen how marketing specs lie. Here are the technical differences you won’t see on the box.

• Protocol Differences: The Netgear EX3700 uses a proprietary protocol for its repeater function that often prioritizes its own nodes over others. The TP-Link RE300 uses standard WDS, which is more transparent but less optimized for Netgear’s specific firmware.
• Local Control: The TP-Link RE300 has a web interface that allows you to disable the AP mode and run it strictly as a repeater. The Netgear EX3700 forces a hybrid mode where the AP and repeater functions are tightly coupled, making it harder to isolate traffic.
• Linux Compatibility: This is where my six years of Linux tinkering comes in. Neither device has native support for hostapd or wpa_supplicant out of the box. However, the TP-Link RE300 is more likely to be flashed with OpenWrt or DD-WRT because of its simpler hardware architecture. The Netgear EX3700 is notoriously difficult to flash due to its locked bootloader.
• Powerline Integration: The TP-Link RE300 includes a dedicated powerline port that allows you to bridge the signal over the electrical grid. The Netgear EX3700 relies entirely on Wi-Fi for backhaul, making it dependent on your existing Wi-Fi signal strength.
• Antenna Design: The TP-Link RE300 has a very small internal antenna that struggles in a basement environment. The Netgear EX3700 has larger external antennas, but they are prone to picking up interference from the 24-bay Synology NAS if it is placed too close.

4. REAL WORLD TESTING — WHAT ACTUALLY HAPPENED

I installed both of these devices in my Portland basement to test them against my four-node Proxmox cluster and my Synology NAS.

TP-Link RE300 Failure: During my testing, I noticed that the RE300 would occasionally freeze when I tried to update its firmware via the web interface. Specifically, after flashing version 1.0.5, the device would reboot into a bootloop if I had my Synology NAS on the same subnet. I had to physically reset the device using the pin on the back. This is a known issue with the flash memory on some TP-Link units when paired with high-bandwidth NAS environments.

Netgear EX3700 Failure: The EX3700 had a strange behavior when I placed it near my Zigbee2MQTT hub. The 2.4GHz band would drop every 15 minutes, forcing a reconnection. I discovered this was caused by the device’s internal clock drifting, which messed up the power save settings. I had to manually set the time via the web interface every time I rebooted the device. This is a common issue with Netgear devices that lack a real-time clock battery.

5. QUICK COMPARISON TABLE

6. PRICE AND VALUE

At the time of writing, the TP-Link RE300 is significantly cheaper, which makes sense given its simpler hardware. If you are building a budget home lab, the RE300 offers more value because you can flash it with custom firmware if the stock firmware fails. The Netgear EX3700 is more expensive, but it offers better range and a more stable connection in my testing. However, the price difference is not justified if you do not need the extra range. Check current pricing before buying, as these prices fluctuate based on demand.

7. WHICH ONE SHOULD YOU BUY?

If you are running a Proxmox cluster and need a cheap, flashable node that can handle powerline bridging, grab the TP-Link RE300. If you need a dedicated Wi-Fi extender for a single floor and don’t care about flashing the firmware, the Netgear EX3700 is the safer bet. But remember, neither of these devices is perfect, and you should consider a mesh system if your network requirements exceed what these repeaters can offer.
