WLAN problems on the iPhone? A small adapter helps!

Many iPhone users know the problem: Laptop, TV and co. run great in the home WLAN network, only the Apple smartphone keeps causing problems. Then you should consider the following solution, which atechbook has tested for you.

If you have problems with the WLAN connection on your iPhone at home, you can fall back on a tried and tested alternative, depending on your home and your needs. For little money, there are adapters for iPhones that allow the device to be connected directly to the router via an Ethernet cable (LAN cable). In the atechbook test, the method delivered great results.

Surfing with iPhone via Ethernet cable

It sounds absurd, but with the right adapter you can connect your iPhone directly to your router. This is not a life hack that anyone has thought up. Apple itself has integrated an option for this in the iOS settings. However, it only appears when the smartphone is connected to the router. This is how it works:

1.) Get adapter and Ethernet cable

Adapters for the iPhone (Lightning to Ethernet) are available from 20 Euros on the Internet. We randomly selected an adapter for our test. The 25-euro device from the manufacturer Unitrox also offers Lightning to USB and Lightning to Lightning. Thanks to the latter, you can charge the iPhone while it is connected to the Ethernet cable, for example. In fact, Apple also offers such an adapter on its homepage. However, Belkin’s device lacks a USB port and costs 99 Euros. That is quite a steep price, especially since a USB-C to Ethernet adapter – for example for a MacBook – is already available for 34.99 Euros. However, we cannot say anything about the durability of the Amazon product compared to the expensive Belkin product. From a purely haptic point of view, the inexpensive Unitrox adapter looks quite light and somewhat fragile.

Many will certainly have the Ethernet cable at home, which is also required. If not, the LAN cable is already available in different lengths for a few Euros.

2.) Connect iPhone to the router

The connection is very easy. Simply plug the Ethernet cable into one of the usually four LAN ports of the router, then connect the other end to the adapter and plug it again into the iPhone.

3.) LAN settings and surfing

As soon as we connected the iPhone to the router, a new item suddenly appeared in the settings. You can now select “Ethernet” under the WLAN settings and assign an IP address and DNS there. Automatic assignment is already preset, so users do not have to do anything else.

If you now deactivate both WLAN and mobile Internet on the iPhone, you should be able to surf via the wired connection. By the way, this is unfortunately not indicated via a corresponding icon. In our test, we had to set the DNS settings to manual for it to work.

No connection problems and higher speed

I did not experience any problems while surfing via the cable connection. It has to be said that the Wi-Fi on the iPhone causes big problems and I often have to deal with disconnections. I therefore switch to mobile data very often. However, there were no interruptions with the LAN connection, just like with all other devices in the household. Since my router is located right by the couch, a super alternative to the wireless Internet connection. However, if the router is not within range for everyday surfing, you can still use the method for larger downloads.

But what about the speed? I made speed tests for this. Once with cable, once in WLAN.

You can see that the connection with the cable has some advantages. The internet connection on the iPhone is not only faster, also the response times (ping) are better than over WLAN.
