I need new switches to go with my Airport Extreme 5th gen. I am use to unmanaged switches from Netgear but are those the best for my Airport? I need a 5 and a 8 port switch. Thanks.
Those are fine. Nothing special about the ethernet ports on an Airport Extreme. Whatever brand you like will be okay.
There is nothing wrong with what you are using. I use TRENDnet GreenNet switches at school and they are great. We have he ones in the metal cases and they are elegant, cool, and stable.
Switches are the only range (IMO) that Netgear make that are any good. I have 8 or so of the managed smart GS108t - some V1 but mostly V2. Probably more than you need but I have also had the unmanaged versions (5 and 8 port). Also worked well. Make sure you get Gigabit versions.
