TP-Link TL-WR845N Review
The TP-Link TL-WR845N is a budget WiFi 4 (802.11n) router designed for basic home internet use where coverage stability matters more than speed or modern networking features. It sits in the entry-level category of single-band routers, mainly targeting small apartments, student rooms, and low bandwidth households that rely on 2.4 GHz connectivity.
Across user feedback and technical listings, it is consistently positioned as a “cheap coverage router” rather than a performance device, and it is now widely considered legacy hardware due to lack of WiFi 5/6 support and gigabit ports.
Who Should Buy
- Users with very basic internet usage like browsing and messaging
- Small apartments or single-room setups with low device count
- Households with internet speeds under 50-100 Mbps
- Students needing a low-cost secondary router for a room
- Users replacing very old WiFi routers for basic stability
Who Should Avoid
- Users with fiber or high-speed broadband connections
- Households with multiple simultaneous streamers or gamers
- Anyone needing 5 GHz WiFi or modern WiFi 6 performance
- Users expecting gigabit wired LAN performance
- Smart homes with many always-connected devices
Unique Buyer Trigger
The purchase is usually triggered when a user only needs “basic WiFi coverage in one area” rather than whole-home networking. This often happens when ISP routers fail to reach a specific room, and the user wants a cheap secondary access point instead of upgrading the entire network system.
The decision is driven by cost pressure, not performance needs.
What Makes This Model Different
The TL-WR845N is defined by its extreme simplicity and legacy WiFi 4 architecture. It provides stable 2.4 GHz coverage but avoids any modern complexity like dual-band management or gigabit switching.
Why NOT other models: modern routers outperform it in every metric except price. It only makes sense when network demands are extremely low and coverage is localized.
Why Buy This Model Instead Of Others
Compared with the TP-Link Archer AX10, the WR845N is chosen only when budget is extremely limited and users do not need WiFi 6 performance or higher speeds.
Compared with newer entry-level routers like TP-Link Archer C6, the WR845N is selected when users prioritize lowest cost over future-proofing or dual-band performance.
The market demand exists mainly in replacement scenarios or very low bandwidth environments where upgrading infrastructure is unnecessary or not possible.
Biggest Strength
Its strongest advantage is extremely low cost combined with stable basic 2.4 GHz coverage. In small environments, it can still provide reliable connectivity for browsing, messaging, and light streaming without requiring configuration complexity or high hardware investment.
It is simple, predictable, and easy to deploy as a secondary or emergency router.
Biggest Weakness
The main limitation is outdated hardware constraints. A common failure case occurs when users connect multiple modern devices or expect consistent performance under load, where congestion quickly leads to latency spikes and speed drops.
Another limitation is the lack of 5 GHz support, which causes interference issues in crowded WiFi environments and reduces usable throughput significantly in real-world conditions.
Position In Product Line
Higher tier: TP-Link WiFi 5 and WiFi 6 routers like Archer C6 or AX series offering dual-band performance and gigabit ports
Current model: TL-WR845N positioned as an entry-level WiFi 4 legacy router for basic coverage use
Lower tier: ISP bundled routers or older single antenna devices with weaker signal stability
Ideal Use Cases
- Providing WiFi in a single room or small apartment
- Acting as a secondary access point for light internet usage
- Supporting basic browsing and messaging devices
- Extending minimal coverage from a main router in low traffic setups
- Temporary or backup networking solutions
Better Alternatives
If your internet speed exceeds 100 Mbps or you use multiple devices, a WiFi 5 router like TP-Link Archer C6 provides far better stability and dual-band performance.
If you want future-proofing and better multi-device handling, WiFi 6 routers like TP-Link Archer AX10 offer significantly improved efficiency and lower congestion.
If coverage is your main issue, a mesh system will outperform this router by providing seamless roaming across multiple rooms.
Final Decision Conflict
Choose the TL-WR845N when your only requirement is extremely low-cost basic WiFi coverage in a small area.
Choose a WiFi 5 router when you need stable dual-band performance for modern households.
Choose a WiFi 6 router or mesh system when performance, coverage, and device capacity matter more than upfront cost.
