If you had more than two devices connected to the 5Ghz radio and you were still having lagging issues, it's doubtful that you'd see any difference with a 3rd party router.
But, a question: When you were trying to stream Youtube videos on multiple devices simultaneously had you turned off, or paused, the Video Data Saver? The Video Data Saver is designed to throttle the speed of the service while streaming in order to save data, but still be enough to stream in DVD quality. When streaming on multiple devices, it's dividing that throttled speed among them, and at that point will most likely be too low on any or all of them to stream anything from Youtube without experience some type of buffering issue.
You can turn off, or pause, the Video Data Saver either in the Video Settings section of the HughesNet Usage Meter, or by signing in to the HughesNet MyAccount site and clicking on Settings.
What is Video Data Saver?
Keep in mind that, while streaming with the Video Data Saver paused or off, you may very well use more data, as things might automatically try to stream in HD.
Also, in case you are not aware, during your first twenty days of service your data allotment is reset on a regular basis. HughesNet does this as a courtesy, to allow new customers to update/upgrade their devices to current without burning through their normal monthly data allotment, as doing those things can sometimes use a lot of data. After those twenty days your data allotment will revert to a normal monthly reset.
