When enabling AGH system freezes, becomes unresponsive and AGH struggles to work. Whole network crashes, I also run WG parallel to AGH. This isn't a single issue, after doing the research, it seems that device is just not able to handle both WG and AGH in parallel. Half baked solution is to extend the memory through swap, which I've done, as there are dozens of people who had this issue, and swapped solved it partially. So far the solution was to TLS to the upstream DNS server which manages my blocking preferencea, however, again, that's half baked solution.
There is an argument "it's AGH's problem and not ours" that some of GL Inet employees expressed, but if you offer a product, make sure it works as customers are paying for things to work. With this much hassle to try and get things to work, my suggestion for anyone who might find this post in the future, is to return this product if you plan to do anything more advanced than Repeater mode and VPN.
My solution is to buy current N100 mini PC, install OpenWRT on it and make things work as they should. This eliminates the weak hardware and awful implementation of AGH on AXT1800 which freezes the whole system. Since I am forced to use Lucy CLI even on this device, I might as well do it on more powerful hardware.
PC in the picture, cost me 140€ which comes with N200, 8GB RAM and 512GB SSD with TDP of 6W. That's the problem I have with this product, if the price difference is 20€ and I still have to do things hard way, I'm doing it on my own terms.
Sorry if I sound frustrated, it is because I am, but it is not at you. I am simply pissed at GL Inet and their non existing support
