TP-Link Deco E4 Design

Deco E4 Design

The TP-Link Deco E4 looks similar to the Deco M4 that we’ve also reviewed, with the tall cylindrical design. Each unit measures 90.7 x 90.7 x 190 mm and feature an LED-status indicator on the top node. If the light annoys you, you can easily turn this LED off, but because it’s so subtly placed, we suggest leaving it on. Unlike the Deco M4, the TP-Link Deco E4 is equipped solely with a Fast Ethernet port. Despite its AC1200 rating, the Ethernet port’s limitations cap the maximum WiFi speed at 100Mbps. Consequently, I would only recommend this model for users with network connections of 100Mbps or slower.

TP-Link Deco E4 Design

1x WAN port and 1x LAN port behind the Deco E4 (100 Mbit each). A power socket is situated at the bottom, featuring a small clip to secure the power cord. It looks clean and sexy overall. It’s also very heavy for a budget router. This weight helps prevent the device from toppling over if your Ethernet cable is rigid. There is no physical WPS button.

TP-Link Deco E4 Performance

Deco E4 Performance

The TP-Link Deco E4 is a Fast Ethernet device, which means it’s more about coverage than speed. I ran the Speedtest. net app on iPhone X supporting Wireless AC1200.

TP-Link Deco E4 Performance

To get a better sense of the Deco E4′s performance, I tested (four times) in four different places: A (next to Deco E4, ~10 feet), B (dining room), C (kitchen), and D (bedroom). Not surprisingly, the Deco E4 maxed out at 100Mbps, meaning it was only a good choice for those with internet connections that are slower than 100Mbps. I believe the Deco E4 is ideal for VDSL users or those on slower broadband plans who desire a Mesh WiFi system for enhanced coverage and a superior WiFi experience.

The sole method for controlling the TP-Link Deco E4 is via the TP-Link Deco App. All Deco devices connect to your TP-Link ID via the cloud, enabling network management even when you’re not at home. The app functions well, and we encountered no issues during use. You can view all connected devices and even monitor their current speeds.

And on the feature side of things, the Deco E4 is pretty barebones as an entry-level model. That said, it does have some useful networking features, such as port forwarding, DDNS and address reservation. It also has guest WiFi and blacklist feature. I’d love to see TP-Link include a network map in here; it would be super handy for the average user.

A highlight is the parental control, which provides an option for fine-grained blocking. We can decide the access level of each user. Except unlike TP-Link’s built-in Homecare parental controls, it doesn’t work on HTTPS-encrypted sites. It also provides a basic Quality of Service (QoS) function, allowing you to prioritise specific clients for faster access.
