Hello everybody!
Today I bought a DIR-879 EXO AC1900 Wi-Fi Router, and I'm sad to say that I'm less than satisfied with it. The first one I bought I had to return, because after upgrading the firmware from v1.03 to 1.05B05 it didn't load certain pages (like the d-link support page, from where I could've downloaded other firmware versions, or the d-link forums with people discussing similar problems, and many more). After some inconvenience I managed to download firmware 1.06B01, which didn't help at all, some pages still didn't open at all, I couldn't download files to my computer (connected via cabel) or to my phone (connected via wifi). I have to mention, that I downloaded the firmware from
http://support.dlink.com/ProductInfo.aspx?m=DIR-879, not through the admin interface of the router. When I try to check for firmware updates there, it says I'm using the latest version.
At this point I returned the router to the retailer, where they exchanged it to a new one that I'm currently using. This time I didn't upgrade the firmware, and it seems to work fine.
This baffled me so much, I had to come here, creat an account and write about my experiences. I'm seriously considering returning this router too, because customer support seems to be subpar at best, since the only answer anybody seems to get at this forum is to contact their regional support center through phone, because it's faster. My other gripe is the firmware upgrade, which makes the router useless, which is a first time for me. I've used multiple routers throughout my life, but never have I encountered an official firmware upgrade rendering the router worthless. There is no indication on the site that the update is regional, or might not work in certain regions, only to check the hardware version.
Some background info: I'm currently in Szeged, Hungary. My ISP is DIGI Távközlési és Szolgáltató Kft., my subscription is for 1000/200 Mbit/s. I'm by no means a network administrator expert, but I've been managing family networks for well over a decade, so I can usually find my way around most problems.
Have a nice day everybody!
