Don't you think that if there is a connection problem with roku to router that it might help to know what that problem is instead of saying well it's you router's problem.
@mayware - That would be the ideal, clearly. However, it is unfortunate, but it is very often the case that consumers' expectations of routers (i.e. they should just work) are not that often met in practice. The potential for problems is vast. Many routers may have specific default configurations applied by the makes for "security" reasons which will prevent things working properly when it comes to media streaming. Other times, a particular make and model of router may go through more than five or six different hardware design revisions in its product life cycle, and there may be multiple versions of the internal software for each hardware version, not to mention different versions sold in different parts of the world (some countries get very different hardware from others sometimes). Each combination may have its own set of bugs, features, quirks, etc., and that is before any adjustments to settings are made by users.
In your defence, you should not need to know this. You should be able to buy a router, a Roku video player, whatever other networked devices you need, and all should happily co-exist. Maybe they will one day. That is not the case today.
It is quite literally impossible for any equipment maker such as Roku, and even much larger companies, to test their product against all popular routers sold over the past year or two, if the many hardware and software combinations are taken into account. So even if they ask you for your router details, and your reply states make and model, that may not indicate to them that there is a problem. They may well have tested against that make and model, but with different internal versions or settings.
Philsoft was trying to point this out, albeit rather more briefly by referencing other router related issues discussed on the forum.
Please don't think I am taking sides with Roku - I am not - I am just trying to explain it a little. I have simply seen many different routers and many strange problems with some of them. Buying from big well known brands is no guarantee that there will not be problems.
