TP-Link TL-SG105, 5 Port Gigabit Unmanaged Ethernet Switch, Network Hub, Ethernet Splitter, Plug & Play, Fanless Metal Design, Shielded Ports, Traffic Optimization

Edit 11/21/2025: I periodically like to perform check-ins on my previous reviews. Over 3 years later I am happy to say this thing still works flawlessly. Haven't encountered a single hiccup. Very consumer friendly and is truly "set it and forget it". ----------------- First off I need to mention that Amazon asked me to rate 3 "features": 'WiFi signal', 'Tech Support', and the 'User Interface'. Let me be clear that this device does not use WiFi and it does not have it's own local IP address to let you log into a "User Interface". Just wanted to point this out in case you come across other reviews that have these two "features" rated that could be misleading you. I recently built a house and had it wired for Cat 6 Ethernet, with there being 1 wall port in each room. One room in particular I have a desktop PC and an Xbox that I wanted both to have a wired internet connection to which is what required the purchase of this device. It is extremely easy to set up, and with it being "unmanaged", there was no portal I needed to sign into that would require me to mess with settings. It's a very simple "plug-and-play" set up, you simply need to connect an incoming ethernet cable from your router/modem (in any port) and then you can now share that internet connection to 4 other wired devices - that's all there is to it. One important note is this: if you have a modem-only device (these devices usually only have a single ethernet port on the back) then you are probably needing a router - not a switch. A router is capable of assigning your devices their own internal IP addresses via DHCP - which is important if you don't know how to assign them yourself. It's also what manages your NAT for situations your devices may need to use the same internet port number. While you don't necessarily need to know what all of this means, you need to understand that a switch is not a replacement for a router. If you are a consumer (as opposed to a business) then you're likely considering this switch to extend/add more ports than what your router has (they usually have around 4 or 5). Even the devices that are connected directly to this switch will still be getting their local IP addresses assigned from your router. The benefit of this switch over a "hub" is that it knows how to route your internet traffic to your devices. So even though it's not responsible for assigning IP addresses to your devices, it knows how to route specific traffic to the devices that require it. It does so lightning-fast - I notice absolutely no additional latency (which is great for gaming) and no compromise in speed either. If you're on the market for a small unmanaged switch, then this is an affordable and excellent choice... A hub, on the other hand, will route all traffic it receives to all devices that are connected to it (they do not 'switch' traffic to specific devices), which essentially requires the devices themselves to ignore the traffic it doesn't want. It adds additional overhead and can potentially cause dropped packets and they just essentially add additional network congestion. I could see a hub being used for something like printers or IoT devices where latency isn't critical, but I think it's ultimately beneficial to just not use them at all even though they might look similar to a switch. And as I've said above, this device does not contain WiFi. You cannot connect this wirelessly to any device. You would be able to purchase a separate device that would connect to this to transmit a wifi signal, but this will not do it on its own.

I’ve been using this connector several days now, and it’s working as expected. I’m using it plugged into a WiFi extender to hardwire our TV and PlayStation. This is giving us faster and more consistent connection. Even though we have fiber internet, the location it was installed in our house is not central, so we’ve had to do the extensions. And our Sony TV’s internal WiFi won’t keep a connection (a common issue for Sony TVs), and game downloads were taking too long as well as not being able to play a live game while downloading. This little box has fixed the issues. It really is just a plug-and-go item. Super easy and you don’t have to be techy to understand how it works. Keep in mind that one port will be dedicated to the WiFi box or extender, so buy the size you need accordingly. If you’ve got 6 devices to connect, you need at least 7 ports. I didn’t know what “looping” was, so after looking into it, I left that switch to “off.” It was not recommended, and warned of slowing speeds and mixing up devices. It’s working great so far. TV connection hasn’t faltered since switching to the box (and not directly into extender box). And the PlayStation downloaded a game in 5mins that, unwired, estimated 30mins! My husband was very happy. He then downloaded Cyberpunk 2077, which is a huge file. When he tried downloading it unwired, it quoted like half a day, lol. Hardwired, it took less than 1.5hrs, AND, at the same time, he was able to play a college football game that uses the network for live play. One thing to note: this did change our IP address, so when we went into Hulu after getting it connected, we got the “it looks like you’re not at home?” message. We had to “update our home location” even though we didn’t really move. You get 4 of these home changes a year, so just FYI. I’m sure Hulu is familiar with this and would work it out if you don’t have any home address changes left, but the hassle and time would be annoying. Overall, I couldn’t be more pleased. If this box stops working after a time, I’ll update my review. But for $12.50 on sale, it’s a steal. The box itself seems quality and well made. It’s got a weight to it and was packaged well. Definitely recommend.

The device works as expected. It is used to split an Ethernet (internet) connection from a router to multiple devices in an entertainment center, efficiently balancing traffic with low latency across all connected devices. Keep in mind that one port serves as the input, while the remaining four function as outputs in this configuration. No setup or configuration is required—the device is truly plug-and-play and works immediately as intended. I recommend this for anyone who wants the accessibility of a network switch without having to program or manage one. This un-managed switch is a great option.

Excelente producto, de alta calidad como siempre en esa marca, no es administrado asi que solo basta conectarlo y funciona perfectamente. No se calienta casi nada y en efecto el ancho de banda es de 2.5 Gbts. Tengo dos y mi red alambrica es perfecta

金属筐体なので質感が良く、放熱も良いです。 1000Mbps出るので、現在の環境では重宝しています。 価格も安いので迷っている方にお勧めです

Fonctionne super bien et de bonne qualité. Par contre j’ai dû mettre plusieurs heures pour la bonne configuration car je n’avais jamais fait ça avant.

Good quality switch, silent running.

Jag fick TP-Link TL-SG105 idag, och efter att ha installerat den kan jag säga att jag är riktigt imponerad. Det är precis vad jag behövde för att utöka mitt nätverk hemma. Snabb installation: Så fort jag packade upp den, var det bara att plugga in och köra. Inga krångliga inställningar eller konfigurationer, vilket gjorde att jag var igång på bara några minuter. Perfekt för någon som inte vill lägga tid på tekniska detaljer. Byggkvalitet: Jag blev förvånad över hur solid och robust den känns. Metallchassit ger ett intryck av hög kvalitet och hållbarhet. Trots att den är liten, känns den som en rejäl produkt som kommer hålla länge. Snabba anslutningar: Även om jag bara har haft den en dag, märker jag redan en stor skillnad i mina anslutningar. Jag har anslutit flera enheter, inklusive min dator och NAS, och allt fungerar blixtsnabbt utan några som helst störningar. Perfekt för hemmanätverk: Om du som jag behöver lite extra portar för att hantera flera enheter i hemmet, är detta ett utmärkt val. Den tar nästan ingen plats på skrivbordet och kör på utan att bli varm eller låta. Sammanfattning: Första intrycket av TP-Link TL-SG105 är extremt positivt. Det är lätt att använda, välbyggt och levererar direkt på prestandafronten. Om du behöver en pålitlig gigabit-switch är det här en perfekt lösning. Jag är riktigt nöjd med mitt köp!
