Fritz Box 5690 Pro Wi Fi Router Review: Real User Experience After 3 Months

When I first unboxed the AVM FRITZ!Box 5690 Pro three months ago, I was looking for more than just a slight upgrade to my home network. I live in a modern household where "passive" internet use doesn't exist. Between my spouse working from home on constant video calls, my own obsession with low-latency gaming, and a growing fleet of over 40 smart home devices ranging from Zigbee bulbs to 4K security cameras, my previous setup was beginning to buckle. I had heard the rumors that the 5690 Pro was the "one router to rule them all," combining fiber (GPON/AON) and DSL in one box while introducing Wi-Fi 7. After ninety days of daily use, I can finally say whether it lives up to the heavy price tag or if it’s just a shiny piece of plastic with too many antennas.

The Setup: Bridging the Gap Between Technologies

The first thing I noticed when I pulled the 5690 Pro out of the box was its size. It’s significantly larger than the aging 7590 I was replacing. It has that classic AVM "shark fin" aesthetic, but it feels more substantial. What really drew me to this specific model was the future-proofing. Currently, I am on a high-speed VDSL connection, but my neighborhood is slated for fiber installation next year. I was tired of the prospect of buying a new router every time my ISP changed the delivery method. The 5690 Pro handles both. I was surprised by how seamless the initial configuration was. I plugged in my DSL line, walked through the wizard on the FRITZ!OS interface, and within five minutes, I was online. What I found particularly impressive was the 2.5 Gigabit WAN/LAN port. Even though my current internet speed doesn't saturate that, I've used it to connect my NAS (Network Attached Storage), and the internal data transfer speeds for my 4K movie library have been life-changing.

In my experience with previous routers, the "upgrade" process usually involves hours of re-configuring static IPs and port forwarding rules. However, I used the FRITZ!Box transfer wizard to move settings from my old device to this one. While it wasn't perfect—I had to re-pair a few of my older smart home plugs—it saved me a massive amount of manual labor. If you are moving from an older FRITZ!Box, this feature alone is worth its weight in gold.

Wi-Fi 7 Performance: Reality vs. Hype

The headline feature here is Wi-Fi 7 (802.11be). I'll be honest: three months ago, I didn't even own a Wi-Fi 7 compatible device. I was testing it primarily using Wi-Fi 6 and 6E hardware. But about a month ago, I upgraded my smartphone to one that supports the new standard, and that is when I really noticed the shift. Wi-Fi 7 introduces Multi-Link Operation (MLO), which allows the device to connect to multiple frequency bands (2.4 GHz, 5 GHz, and 6 GHz) simultaneously. In my testing, this translated to a level of stability I haven't felt before. Usually, when I walk from my office to the kitchen, there’s a slight "hiccup" as the phone handovers between nodes or bands. With the 5690 Pro, that jitter essentially vanished.

One thing that bothered me initially was the 6 GHz range. Like all 6 GHz implementations, it’s quite sensitive to walls. If I’m in the same room as the router, the speeds are astronomical—peaking at around 2.4 Gbps on my local network tests. However, if I move two rooms away, the phone naturally drops back to the 5 GHz band. The good news is that the 5 GHz performance on this unit is the strongest I have ever measured. Even through two brick walls, I was pulling 600 Mbps on a 1 Gbps line, which is significantly higher than the 350 Mbps I used to get. I noticed that AVM has really optimized the antenna array; the beamforming seems much more aggressive at targeting devices that are at the edge of the range.

The Smart Home Hub: Zigbee and DECT

For years, I’ve had a separate hub for my Zigbee smart bulbs and sensors. It was another thing to plug in, another point of failure, and another app to manage. The 5690 Pro integrates Zigbee directly into the router. I was skeptical about this—all-in-one devices often do many things poorly rather than one thing well. To my surprise, the Zigbee integration is robust. I was able to pair my existing Philips Hue bulbs and Ikea Tradfri sensors directly to the FRITZ!Box. The interface shows them alongside my DECT handsets and smart plugs. One disappointment a real owner would notice, however, is that the Zigbee implementation isn't "all-inclusive" yet. Some specialized sensors from niche brands didn't report all their data correctly (like a specific humidity sensor I own), but for lighting and basic plugs, it worked flawlessly. Getting rid of an extra bridge in my hallway made my tech cabinet much cleaner.

Daily Reliability and Thermal Management

After testing for three months, the most important metric for me is "uptime." A router is only good if you never have to think about it. I haven't had to manually reboot the 5690 Pro once since the initial setup. Even during a heatwave last month where my office reached 30 degrees Celsius, the router stayed cool to the touch. The vertical design seems to act as a natural chimney for heat dissipation. I've used routers in the past that would throttle speeds or drop the 5 GHz band when they got too hot, but the 5690 Pro remained rock solid.

I also spent a significant amount of time diving into the FRITZ!OS 7.80 (and later 8.00) features. If you are a power user, you’ll appreciate the "WireGuard" VPN integration. I set it up so I could access my home security cameras securely while traveling. The setup was as simple as scanning a QR code on my phone. The throughput over WireGuard was impressive; I was able to stream high-bitrate video from my NAS while sitting in a hotel room five hundred miles away without the router breaking a sweat.

Comparative Analysis

To give you a better idea of where the 5690 Pro sits in the current market, I’ve put together a comparison based on my personal observations and testing against other high-end models I’ve used or trialed recently.

Pros and Cons After 3 Months

Every piece of hardware has its quirks. While I am generally thrilled with the 5690 Pro, there are specific things that might make it the wrong choice for certain users. Here is my breakdown of the hits and misses.

Pros

• Extreme Future-Proofing: Having both Fiber and DSL ports means this is likely the last router you will need for the next 5-7 years, regardless of how your local infrastructure changes.
• Incredible Throughput: Wi-Fi 7 is no joke. Even on older devices, the antenna design provides a more stable and faster 5 GHz connection than previous generations.
• Integrated Smart Home: The addition of Zigbee is a game changer for reducing "hub clutter." Managing everything from one dashboard is intuitive and efficient.
• Excellent Software: FRITZ!OS remains the gold standard for home networking software, balancing ease of use with deep "nerd" settings like spectrum analyzers and detailed energy monitors.
• NAS Capabilities: While not a replacement for a dedicated Synology box, the USB 3.1 port combined with the 2.5 Gbps LAN makes it a very capable media server for the average family.

Cons

• Physical Footprint: The device is tall and wide. It won't fit in small media cabinets or behind thin TV stands as easily as its predecessors.
• Price: It is a heavy investment. If you only have a 100 Mbps connection and five devices, you are paying for performance you simply won't use.
• Zigbee Limitations: While great for lighting, it doesn't yet support every obscure Zigbee sensor on the market. Check compatibility if you have a very complex smart home.
• Omitted 10Gbps LAN: While it supports 10G fiber input, it only offers a 2.5G LAN port. For 99% of people, this doesn't matter, but ultra-power users might find it a bottleneck for internal wired networking.

The Buying Guide: Is the 5690 Pro Right for You?

Buying a flagship router like this is a major decision. Based on my experience, I’ve identified three types of people who should seriously consider this upgrade, and a few who should probably skip it.

Who Should Buy It?

First, if you are a "Tech Transitioner"—someone who currently has DSL but knows Fiber is coming to your street soon. This router prevents you from having to buy twice. Second, Power Users and Gamers. The low latency on the 6 GHz band and the native WireGuard support make it a dream for anyone who cares about ping or remote access. Finally, Smart Home Enthusiasts. If you want to consolidate your hubs and start using Zigbee without the extra cables, this is the most elegant solution currently on the market.

Who Should Skip It?

If you live in a small apartment and your internet plan is under 250 Mbps, this is overkill. You would be better served by a smaller FRITZ!Box or even a simple mesh system. Also, if you have no interest in "tweaking" your network and just want a box your ISP provides for free, the depth of features here will likely go to waste. You are paying a premium for the software and the hardware versatility.

Things to Consider Before Purchase

Before you commit, check your current devices. Do you have anything that can even see a 6 GHz network? If not, you’re buying this purely for tomorrow, not today. Also, measure your space. Ensure you have enough vertical clearance for those antennas to breathe. Lastly, consider your wired needs. If you have an entire house wired with Cat6a cable, be aware that you only get one 2.5 Gbps port; the rest are standard Gigabit. You might need an additional multi-gig switch if you have multiple high-speed wired devices.

Final Observations and Verdict

What I found after ninety days is that the FRITZ!Box 5690 Pro is less of a router and more of a "network coordinator." It has become the silent heart of my home. I noticed that I stopped checking my speed tests after the first month—not because I stopped caring, but because the connection became so reliable that the "need" to check vanished. That is the highest compliment I can pay to a piece of networking gear.

I was surprised by how much I ended up using the DECT telephone features, too. I didn't think I needed a landline, but the ability to use my smartphone as a home phone handset via the FRITZ!App Fon, connected through the 5690 Pro, actually improved call quality in areas of my house where cellular signal is weak. It’s these "hidden" ecosystem benefits that really make the AVM experience different from buying a standard gaming router from a big-box store.

In my experience, many flagship products trade reliability for "bleeding-edge" features that often crash. The 5690 Pro is different. It brings the cutting-edge Wi-Fi 7 and Zigbee standards to the table but wraps them in the legendary stability of the FRITZ!OS. It’s a expensive, physical statement of a router, but for anyone who relies on their internet for work, play, and home automation, it represents a significant quality-of-life improvement. If you have the budget and the need for a "do-it-all" machine that won't require an upgrade for many years, the 5690 Pro is, in my honest opinion, the best consumer router currently available on the European market.

The transition from "high-end Wi-Fi 6" to "Wi-Fi 7 with integrated smart home" felt like moving from a reliable sedan to a luxury electric vehicle. There’s a learning curve if you want to use every single feature, but even if you just plug it in and let it run, the performance ceiling is so high that you likely won't see a "Buffer Underrun" message for a long, long time. After three months, it has earned its permanent spot on my desk.
