The maximum speed stays around 2Gbps when connecting a 2x2 radio to a 4x4 base station. A 4x4 radio linked to a 4x4 base station can reach about 3Gbps. Using the M1 chip appears Apple reused the same processor found in iPads for Macs. I observed no VHT160 support but did see 802.11r compatibility on WPA2 Personal networks, similar to what iOS devices offer. However, I’ve experienced issues with the M1’s wireless chipset not functioning properly with VHT20 channels, causing packet drops across various AP models and brands. It seems Apple likely omitted VHT160 support in the M1 radio due to limited consumer router compatibility and its rarity outside enterprise settings. Until recently, in the US, using 160MHz channels often needed DFS channels, which most routers don’t support or certify.
What bothers me is managing two 2x2 MU-MIMO clients together—they still managed roughly 1.4Gbit. It’s possible my setup was off, or one of the devices wasn’t truly MU-MIMO. I noticed several reports suggesting MU-MIMO introduces too much overhead, making it ineffective. I wasn’t surprised to see only partial performance compared to regular MIMO, where data splits evenly. You might be right about DFS limitations; some devices didn’t support it well, and those that did performed poorly. This reinforced my move toward Enterprise APs with NanoHD and the NWA210AX. Even with support, consumer gear often misinterprets DFS and fails to maintain proper channel transitions (like dropping to channel 36 without returning). To be honest, I thought the price tag justified it since the NWA is significantly more expensive. Before that, I relied on OpenWRT, which also struggled with DFS for a long time.
I understand the desire for quick download speeds, but if you truly need that level of bandwidth, you're likely already set up with a solid connection and the right gear—otherwise, it's not wasted effort for regular users. Most consumer devices still come with limited networking capabilities, which is why many people don't push this further.
Yes. The False DFS hits are a recurring issue I face with many vendors, including Ubiquiti. It often happens when low-cost Android devices use Wi-Fi probes and accidentally activate the DFS detection system. I've also noticed certain Wi-Fi hidden nodes cause it to trigger when they appear or disappear. There was a known problem with 160MHz wide channels in 5GHz bands that caused the DFS radar to react too quickly. Regarding UniFi APs, I recall some firmware versions where the devices would remain stuck on Channel 36 and refuse to switch back. Based on my experience, they have a 24-hour delay before returning to the DFS channel, which appears to be functioning well recently. For devices that don’t support DFS—like Roku or Smart TVs—I’m frustrated because they often use inexpensive wireless radios (typically single-input single-output models) and skip proper DFS certification. Despite DFS being widely supported on ISP routers and premium consumer hardware, this remains a concern. In enterprise settings with many IoT devices, the situation gets worse since these systems are frequently set up to prioritize DFS due to high client density. It’s undesirable if IoT gadgets connect to unintended distant channels. The MU-MIMO issue is tricky; it mainly affects downlink traffic on most modern devices (especially 802.11ac Wave 2). Uplink wasn’t considered until WiFi 6, and it’s uncommon for a device to have only downlink without any uplink. Ethernet broadcasts and multicasts usually cause this problem, which shouldn’t occur on Wi-Fi links unless multicasting is actually happening at the right rate (54Mbps max, 1Mbps min). I’ve seen MU-MIMO make a noticeable difference in ultra-dense environments with a mix of 1x1 and 2x2 devices, where consistent bandwidth flow helps. If APs or radio drivers could reveal MU Grouping data, it would clarify whether MU-MIMO is just marketing hype or actually effective.
You can link the external fiber directly to the Unifi Dream Machine instead of using the Nokia box, and you can also disconnect the ISP router. For blocking your ISP from tracking your activities, consider using UXG Pro to enhance privacy while maintaining faster speeds. Regarding extra features for Ck-Enterprise, it offers added security benefits beyond standard plans. Let me know if you need more details!
You can't take out the Nokia device, but you might be able to replace their router yourself. This depends on its functionality and whether they give you access details.
