The Huawei E5186 has the WiFi button and WPS button with the reset hole at the below side of the SIM card slot. The Huawei B612 power button is at the top side with WPS button. They both have two connectors for external antennas. The connector type is SMA and covered by a cap.
Huawei E5186 VS Huawei B612 Specs and Features
The two routers Huawei B612 and E5186 are both in the typical design of Huawei 4G wireless router. Then let’s compare the specifications of Huawei B612 and Huawei E5186 to see more difference:

Summary
From the specs table, we can see the two Huawei Cat6 routers both could achieve peak download speed up to 300Mbps. They both have two variant models now. The Huawei E5186 supports dual-band WiFi while Huawei B612 supports only a single band on 2.4GHz. Huawei E5186 router could support up to 64 wireless users while Huawei B612 supports up to 32 WiFi users. However, the Huawei B612 supports 4 x 4 MIMO technology while Huawei E5186 supports 2 x 2 MIMO. Except for the interface difference, the MIMO technology should be the key difference.
One more thing we have to mention is that perhaps the Huawei B612 is a latest new model, the price is more expensive, but we suppose the Huawei B612 price would become cheaper soon. If you want to buy a 4G LTE modem router, we think the Huawei E5186 is very good to recommend based on the price/performance ratio.
