Are there any consumer-grade wifi routers that make some attempt at, and to some degree succeed at, fair bandwidth allocation?
By “fair” I mean something like, if there are 20 users sharing a wifi router, including a few bandwidth hogs, then the capacity available to the low-bandwidth users drops to approximately 5% each (rather than 1%, or even 0% for minutes at a time, which I’ve seen is common).
If there are such routers, then my questions are (a) is there a technical term for this feature, (b) how to do a search for routers having that feature, (c) how to look up, for a given brand/model, whether it has that feature, (d) if it has that feature, how to tell whether it’s the default configuration vs. requiring minimal configuration effort (e.g., settings via the admin login) vs. requiring extensive configuration effort (e.g., DIP switches, new firmware, etc.). I’m talking about how to get this information when looking up routers online and not having the physical product in hand.
This is so I can advise non-technical personnel (such as manager of coffee shop or small hotel) on getting a router that ideally does the right thing out-of-the-box, and/or advising them on whether they have the right router already (and just need to select a setting). If the router came with manuals, they may have been discarded or lost already.
