Routing throughput running the latest 3.13.4 Build 110429 Rel.36959n firmware and our router test process measured 123 Mbps WAN to LAN, 113 Mbps LAN to WAN and 121 Mbps total with up and down tests running simultaneously. The IxChariot composite plot in Figure 5 shows download gets a bit more throughput than upload in the simultaneous routing test.
The maximum simultaneous connections test yielded only 5,109 connections, with the router locking up temporarily after that limit was reached. I didn't have to reboot to get things moving again, but just had to wait a bit for some of the sessions to die off.

The TL-WR1043ND is Wi-Fi Certified but did not properly default to 20 MHz bandwidth mode on power-up. I successfully ran a Wi-Fi Protected Setup (WPS) session with my Win 7 client by entering the WPS code found on the router's bottom label. The WPS session completed quickly and resulted in a WPA2/AES secured connection. All tests were run with this secured connection using our latest wireless test process.
Because of the problems we found using our standard Intel 5300 test client with only two antennas connected, we've made a change in standard test client. We're now using an Intel Centrino Ultimate-N 6300 in a Lenovo x220i notebook running Win 7 Home Premium. This client will be used for all wireless testing, except when we need to run dual-stream tests on three-stream routers/APs. In that case, we'll use the previous standard Acer Aspire 1810T notebook that also runs Win 7 Home Premium. But it now has a proper dual-stream N client installed, an Intel Centrino Advanced-N 6200.
I filtered the default 2.4 GHz downlink benchmark chart to show only single-band routers. Figure 6 shows that the TL-WR1043ND doesn't do too badly. But its ranking in the uplink benchmarks is much lower, falling to the lower half of the rankings.

For a comparative look, I chose two other inexpensive single-band routers with Gigabit ports, the EnGenius ESR9850 and Buffalo WZR-HP-G300NH. Figure 7 shows only occasional wins for the TP-LINK, both for downlink and both in mid-level signal test locations.
Figure 7: Wireless Performance Comparison
You can see overall poor uplink performance and also that throughput is very low in the weakest signal test location F. Highest throughput of 85 Mbps was measured in Location A, in 40 MHz mode running downlink. I was able to measure 98 Mbps of total throughput in a Location A simultaneous up/down test using 40 MHz bandwidth mode.
The bottom line is that this is not a router that is going to provide exceptional uplink performance, nor will it be especially helpful for extending your wireless range.
The IxChariot plot in Figure 8 shows relatively stable throughput, which was generally the case.

For a top-of-line router, the TL-WR1043ND's performance isn't particularly impressive. But for a $55 single-band N router with Gigabit ports, it isn't too bad.
