Swapping the laptop antenna can enhance Wi-Fi stability.
The Wi-Fi in my dorm often drops unexpectedly, making it hard to focus while studying. I’m thinking about swapping out the antenna on my laptop to fix this. For a Gen6 X1 Carbon running Ubuntu, which antenna would work best? If you’re not using one, what kind of external adapter should I consider for a quieter connection?
It's uncommon for your phone to experience issues regularly.
I might not own an old router. I'll look again when I get home. Also, would I need to connect it to an Ethernet port? Because if so, it would have to be exposed in a difficult location. There are varied opinions on whether schools permit routers from Reddit.
Laptop Wi-Fi cards tend to be less dependable than mobile devices, particularly premium phones. An external antenna generally offers better performance than internal ones. For maximum reliability, opt for models with physical antennas. TP-Link provides these via USB connection. If a slim design is preferred, choose compact USB dongles suitable for mice or keyboards.
I don’t think USB adapters are always reliable. I’ve only owned one that performed well, because I was searching for a particular chipset at the time. Even then, it didn’t match the variety of laptop adapters available. The issue isn’t necessarily the adapters themselves, but rather the drivers. Some might use the same chipsets found in routers, but those rely on closed-source software tuned for a specific kernel version. Linux, on the other hand, uses open-source alternatives. In laptops, manufacturers sometimes place antennas in awkward spots—like on the wrist rest—which can block signals. While screen mounts are more common, the best placement depends on the device’s design; they’re hard to swap out once integrated. Low-profile adapters tend to be inexpensive and often not very good. I’d like to know what kind of WiFi adapter this laptop has and see if a better option exists.
Many other users could be connected through the network. If the access point becomes too busy, changing it won't help. Also, students often set up their own routers or APs, which may interfere with the school's WiFi signal. Use a wireless scanner like WiFi Analyzer on Ubuntu to check the 2.4GHz and 5GHz bands. The X1 Carbon Gen6 usually comes with either Intel Wireless-AC 8265 or 9260 chips—good options. The antennas are usually built into the laptop screen, so they might not be easily replaceable. I'm not sure if Ubuntu provides solid drivers for those older cards. Try switching to another operating system to see if the problem persists.
