The E2500's hardware is v1.0 and the firmware is v2.0.00.

Devices that are working flawlessly with this router include:

iPhone 6 Plus
Huawei Nexus 6P
Samsung Galaxy S5
MacBook Pro 13" Mid-2012
RTL8192CUS-based USB WiFi dongle

I have never had any connection issues. My other laptops have been able to remain connected with open SSH sessions to remote systems for days at a time without disconnecting. I should mention that I now make sure to ping my router, not the Internet, to check if the WiFi interface is working properly. Since my Internet is reliable, it doesn't make much of a difference, but this way, I eliminate potential error sources.

The USB dongle listed last was purchased today and is plugged into the Lenovo as a workaround for WiFi until it's fixed. It works perfectly fine if I use the rtl8192cu-fixes driver. I unplug it whenever I test the internal WiFi for this bug ticket.

(Is it just me, or are all the Realtek WiFi drivers in the kernel kind of unreliable? This is not the first time Realtek chips have given me trouble.)
