D-Link AX3000 5G Cellular Gateway WiFi 6 Router, Optimized High-Gain Antennas, Dual-WAN Failover, Parental Controls, Enhanced Security, AT&T Certified (G530)

Last month I purchased the D-Link AX3000 5G Cellular Gateway for my small business because our office building management company charges too much and the connection wasn't stable. I initially had concerns about signal strength because we are on the 10th floor; however, the AX300 has become an essential networking device. We tested two SIMs from different wireless carriers and both provided strong 5g connections. We haven't experienced any lag or bandwidth issues when multiple employees are simultaneously dialed into video-teleconferences. We also configured the VPN for after hours remote access to our LAN. So far I've only used it in our office but if we all go on a business trip together, then I may take the cellular gateway on the road with us. Overall, the D-Link AX3000's versatility, performance, and reliability have exceeded my expectations, which made it a perfect cellular device choice to meet our video-teleconferencing, remote server access, and other connectivity needs.

I read a comment from another use that stated they had no issue with T-mobile but was wondering if they were actually on a business plan. From discussions with the T-moble tech support, the answer I got was this device, or rather the sim card issued for their equipment, would not work in this device, and did not with the numerous attempts on my own, including manipulating the APN settings with tech provided info. The business plan Definity will allow for this device to operate but I do not have a business account to verify. I will say that the interface does offer a lot of options for security controls and operations. I was just disappointed that T-mobile does not allow the same options for home users. I would recommend the product for T-mobile small-business users based on the stated data increases and security options.

I have extensive experience with networking and devices so I might be more critical than the average user. It took 3 tries to setup the device with the phone app crashing and and a long unnecessary process. The app/firmware are lacking: -Need to control the notifications for different events, how they are sent, and at what intervals. -Need more control over the failover and return to the main network. -Need to see advanced features remotely when not on the same network. Clicked on the Support link on their website and it's a dead link. Tried to complete the Contact Us form and when you submit that doesn't work too. If I can't get some hope for a firmware and app update I'll be sending this back.

Everything has been great so far, however, it would be nice if it came with the ability to attach an external antenna. It is way more reliable and convenient than using smart phone tethering.

I am an IT professional with both military and civilian experience who recently retired. I purchased this 5G gateway for travel in my Class B camper van and as a backup for home internet. I had difficulty using the included SIM card as it never fully connected to the 5G cellular service. I sent email to support and they responded in a day that I needed a firmware upgrade. I was sent the link, upgraded the gateway, and then it worked as expected. The mobile app works on my Pixel 8 Pro, the text is small but usable. In central Florida I used the gateway to get 5G service, previously I had 4G LTE service only from my Pixel hotspot. My primary cellular service is via the T-Mobile network from Google. Thus, I am a very satisfied owner of this D-Link 5G gateway and the support for it.
