NETGEAROmnidirectional MIMO Antenna (6000451) - Boosts Performance of Internal Antennas, Compatible with M5 (MR5200) & M6 (MR6150 & MR6550) Hotspot Routers, Includes 2 TS-9 and 2 SMA Connectors

Works with regular M6. Paired with cable extenders is perfect when having your device indoors with outdoor reception. Mine is placed on a window and the differences are notable for my overseas trip as max 4g speeds where I'm at are 25mpbs (non peak hours). So any extra reception is noticeable otherwise i would have to leave my hotspot outside to the elements. Worth the purchase.

Works great. It does improve signal strength

Tried to use this antenna in an apartment building, above ground level, but it actually made the signal from my Netgear M6 router worse not better. Returning product.

At first I thought that it was not working properly, since this antenna has the same number of bars as the antennas that came with my modem and I was about to return it. However a speedtest showed that the download speed increased from 18mps with external coil wire antennas to 24 mbps with the netgear. I will probably keep using the coil antennas when we are out camping and cellular reception is poor to none exsitent and keep the netgear around the house when I use the 4g as failover solution.

I got the NETGEAR (600451) Omnidirectional MIMO Antenna to use with my MIFI 8800L Hotspot. You will have to adjust to your surroundings as you use it. In some areas, your internal antennas will work better, whereas in others, the antenna will help boost your signal.I like the small form factor, and it is about the size of a hand with the fingers spread out or a small paperback book, and it is light to carry. It does come with two ways to mount it. It has two suction cups to mount to windows and it has two brackets that will allow you to hang it on your open laptop or a flat surface like a laptop.

We use these with our mobile hotspots for our Photo booth business and they work great! We get a signal where normal antennas have none or very weak. Also seems to give more life to the wifi network as well. Easily adds 2 bars to the cellular signal. Worth it.

Pros:• Can connect to existing wifi (i.e.: starlink, campground wifi, starbucks wifi, etc, a.k.a. data offloading), to re-distribute internet to your personally created wifi network or LAN• Has an ethernet port for LAN• Has split 5Ghz/2.4Ghz wifi broadcasts (some devices don't like when they're combined)• Allows VPN tunnelling• Access to text messages sent to SIM card/phone number, which is useful for 2FA, carrier messages, etc.• Allows IP Passthrough (the router acts as a modem solely)• Allows enable/disable of DHCP service from router• Has 2 radio antenna extender portsCons:• Display is nice, but tough to use. Better off using the web page.• DNS settings would NEVER work for me. It has a section where you can set a DNS IP, but no devices would ever get these IPs. I know some routers set themselves as the DNS provider, then forward all requests to the IP you set, but not this router. I could not access my pihole or other LAN devices via FQDN, only IPs. That kind of sucks.• Every single change requires a reboot. EVERY. LITTLE. CHANGE.• Every reboot, the system would NEVER turn back on. Its almost as if "reboot" = "shutdown". Keep the device within reach if you plan on making any changes.• Drops packets every 45 seconds or so. I ran a continuous ping to google.com and it resolved the IP no problem, ran the pings no problem at around 30ms each, but then it'll just jump up to 250ms, then "Request timed out" once, then back to normal. 45secs later, it'll jump to 250ms, then "Request timed out", and so on. Seems like it can't handle a normal workload. For comparison, I connected to my Starlink router in the same location, ran a ping to google.com and never had any dropped packets or "Request timed out" replies.This is a secondary form of internet for me now as it's performance is hardly reliable. I can't set DNS to be my pihole, and I really don't feel like setting DNS individually for all my wifi devices. I can't have consistent internet if the router is underpowered and dropping packets.Too bad I'm outside my return window now, otherwise I would have returned this.

Have a Netgear M6 in my RV and often don't need this antenna. But it's a must if you go way out into the boonies, which we do. I can't say it doubles the cell reception, but it dramatically increases it, and it's noticeable. The M6 is quite good on its own so most of the time you want to let it's build in antenna do the job, and attach this only when you need the extra help.
