Question 1

Does the er840g have a usb port?

Accepted Answer

I just received the er840G and it does NOT have a USB port.  That was one of the features I wanted.  I reported to seller, and am contemplating returning device.

Question 2

I need to connect 500 devices. Can this device handle 500 devices?

Accepted Answer

I would not recommend this for 500 devices. There would be better enterprise grade units I would recommend over this.

I start see 50% hardware utilization with ~70 simultaneously connected devices. Much more I would think would cause noticeable slow down.

The router does support multiple subnets, so I suppose you could technically connect that many devices, but i would suspect degraded performance if all users attempted to use simultaneously, it just would need a beefier processor and a little more ram.

Question 3

If i set this up in load balancing mode and one of my isp links goes down, will the device re-route traffic through the one remaining uplink?

Accepted Answer

Yes, it should automatically do that.  I have it setup for two WAN connections, to do this function explicitly. That's why I purchased this product, and its price/performance ratio, compared to other brands with similar function. To test load sharing in general, I restricted/throttled bandwidth for the UTT to share the two WAN ports at the same time, using the firmware in the device -- sometimes it worked properly, and lately it has not worked  properly (I measured bandwidth at speedtest-dot-net and compared to UTT settings)

Question 4

Do you offer a model with full gigabit throughput?

Accepted Answer

Hi there,

The maximum ISP bandwidth supported for now is 600+Mbps by the model UTT ER4240G.
We thank you for asking and please feel free to email support@uttglobal.com if there is any other question related to our products.
