Tp-link Dual-band Wireless :: Wifi Unstable On Tl-wdr4900?
Apr 3, 2013
Region : Netherlands
Model : TL-WDR4900
Hardware Version : V1
Firmware Version : 121211
ISP :
after changing from a Thomson router with wifi to the TP-link WDR-4900 I find that the wifi is very unstable. The 2.4GHz is operating on the same channel as my previous router (channel 8 - which is the lest busy channel around my house), and none of my neighbours have wifi on the 5GHz band. Almost all devices in my home regularly have to reconnect to the wifi, both on the 2.4GHz as on the 5GHz (tested with more than 8 devices). Almost every 15 minutes I see a "wifi channel disconnected" message, 10 seconds later followed by a "wifi connected" message. the Wifianalyser app on my tablet confirms that the wifi signal drops once in a while to zero. I use the latest stable frmware (I read that there is beta firmware but I don't like to loose warranty). The stability seems to unrelated to the amount of traffic on the wifi network.
Will this be fixed in the next firmware of the TP-WDR-4900 ?

I have upgraded to the latest firmware which solved lots of problems regarding unstable wifi connection as well as BitTorrent / P2P transfers.But I also observed that when my BT is on (Transmission for Mac) at around 50KB/s upload and download, my network latency hikes up from some 30ms to 500ms which affects a lot on web browsing or other apps requiring Internet.My BitTorrent app is showing I am merely making some 20 peers connection so I am not convinced that is an ISP problem but it's more about the router.

I have bought tp-link wdr-4900 for several days and encounter the following problems
1) nfs is not work, whenever I set up the nfs server (using hanewin nfs server), the media player fails to read the media file. (Problem does not appear for the previous ASUS n56u)
2) When there is large traffic rate (e.g. BitTorrent), the whole machine is very unstable, LAN and Wireless dies (SSID disappears, and LAN appears "ERR Connection" and "DNS not respond"), give me a feeling that the router cannot handle high traffic rate and the whole machine slows down and fails.

I have some linksys router that I used as wireless client bridge. I have main router that is connected to Internet and linksys router which is connected to main router's WiFi. Linksys router acts as client bridge connecting LAN devices to main router. Now I own TL-WDR3600 and I would like to replace linksys router. How can I achieve the same on TP-Link router? I don't see any option for setting wireless operation mode.

This router worked fine until I updated the firmware downloaded from the TP-Link site. I have V1 hardware which is what the firmware was created for. Since the update the wifi continually kicks outs quite often rendering this router useless.

Firmware Version : OpenWRT

I was having major stability issues with my TPLink WDR4300 and after a little bit of research, decided to upgrade the firmware to OpenWRT. I found a post online and followed these instructions:
1- Make sure your router is version 1.x (x can be any number).
2- Download the openwrt firmware from here: [URL]
3- Download putty command tool from here: [URL]
4- Login to your router config page (192.168.0.1) using internet explorer browser and update the firmware to openwrt. Use the firmware file you downloaded in step 2.
5- Now open Putty software you downloaded in step 3. Enter host name: 192.168.1.1, Connection Type choose: Telnet. Now click open. Now you will see the command line with black screen,
6- Now type "passwd" into the command line and press enter on the keyboard. Now choose your new password to access the router make sure password has letter and number. Repeat type password and press enter. Password should be changed now.
7- Type into the command "opkg update" and press enter on keyboard, Wait for it to do some download and updates. Once finished, type this "opkg install luci" and press enter
8- Type this into the command to enable luci "/etc/init.d/uhttpd enable" and press enter on keyboard.
9- Type this into the command "/etc/init.d/uhttpd start" and press enter on the keyboard. Now you can close Putty.
10- Open internet explorer in the address bar punch in: 192.168.1.1 and use the password you created to login to the router config page. Go to the wifi section and turn on the wifi and set up wireless security network.
Everything worked fine until I got to the last step and go to the "wifi section and turn on wifi." After a bit more digging, I noticed that there is not a "Wifi" option under the 19192.168.1.1 portal "Network" tab. After getting frustrated and more hours trying to figure it out, I elected to try and go back to stock firmware. On Luci, I selected restore to factory settings and the router did its thing and restarted. Now I can't login to Luci (obviously) since it was no longer enabled in Putty. I try and run Putty to connect to 192.168.1.1 and it just opens and immediately closes. It will not connect. I also can no longer login to (192.168.0.1). Further, when I try and run the TPLink setup disk,I receive the error "Please check the network connectivity" and "Please check the model of your router." The Wifi light on the router does not turn on (it is switched on). I'm stuck and don't know what to do! I use this router in a home office with multiple wifi users.

I note that my 4300 never uses two channels in 2.4 GHz wireless n mode as reported by Inssider. I can see a few other routers on Inssider, one of which uses channel 11+7 ALL the time, though it's not a TP-Link router. Mine sometimes will connect to two channels, thus enabling 300 Mbps, but then quickly drops to 1 channel. I believe this is a firmware fault as I only have 3 or 4 routers in the area of my house and I can't believe this would generate sufficient interference to force the router to run at a lower speed. If the router does behave this way by design, then TP-Link should stop advertising it as a 300 Mbps router as it will almost never operate at that speed.

I can't able to recognize a system - all wifi clients lose connection. When this happens, the ping answer time rech the ~2000 times, then totally lose the connection, the SSID is dissapear - checking with my phone (android - wifi analyzer) and TL-WN822N USB wifi adapter (with the inSSIDer application). Meanwhile the cable clients and the WAN connections works fine, didn't experience anything.If I restart the wifi service with the hardware on/off button, it runs well for some time.This problem appeared when I used the two older official firmware too.
I tried the auto-chanel function width auto channel width, tried to manually set up one of the less interfered channels with both 20MHz and 40MHz channel width, but none of them bring the solution.The intresting thing is, if I change the router with an old D-Link DI-604, the signal is weak, but the wifi connection is stable, with the same TL-WN822N adapter.I tried to guarantee the router, but after two weeks, my reseller said, it looks ok, they - at the TP-Link service - didn't find anything.

I'm using a WDR3600 router, and I'm having difficulty with getting internet access on the 5 GHz band. Right now the router is broadcasting in both 2.4 and 5 GHz as two separate APs. The 2.4 GHz band works perfectly fine, but when I connect to the 5 GHz band my device is not assigned an IP address and cannot connect to the internet (or even the router configuration page). Unfortunately, I don't have another device capable of accessing the 5 GHz band, so I can't check to see if the computer is at fault, but both the computer and the router have worked together with no problems before, and this computer has done fine in accessing other 5 GHz bands.

I just upgraded my DLink DIR655 to WDR4300. My VOIP service has worked for the last 5 years. But with WDR4300, I'm frequently experiencing dropped calls. The call will be cut off every 20 seconds or so. This is really a deal-killer.

I have no problems connecting on a 5 GHz band or wired to the router. However any device connecting on 2.4 Ghz gets barely any bandwidth and drops after running for a short time. I have test numerous devices and have the same issue. What was odd is a device on 5GHz that worked fine had the same issue when connecting on 2.4 GHz which seems to say it is only that band. I have an old router that works fine on 2.4 GHz on channel 1 with all the security settings I used on the 4300.

Get GMT throws an error. I set known good public NTP servers, still get error. Also power cycling or rebooting the router seems to drop manual time settings, as well. I am using WDR4300 as a wireless access point, does that matter? Maybe I don't need time in access mode? It is connected to the Internet and is providing internet access to clients.

I have an issue with my TL-WDR4300 (regular, internet sharing use, no Open WRT or similar things). It was working well, until one day that my devices only receive the 2.4 GHz signal (no 5 GHz) and then I try to connect to 2.4 GHz and it asks for a password. I put my regular password and it doesn't work. Then I tried to bring it to factory default settings, I push the reset button for 8 seconds as the manual points and then same thing. What could I do?

ISP : I have an external HDD that I regularly use in any computer I have access.It's an HDD enclosure 2.5" 3.0 USB, with a 750GB WD HDD inside. I use it in computers with all versions of USB, even in my TV. It doens't require an external power source, and just have 01 input/output, which is a USB port.After plugging it in the router (running with the last available firmware from TP-LINK - 3.13.27 Build 121207), I entered the setup screen of the router, and under USB Settings, pressed RESCAN, but the HDD wasn't recognized.What happens is that when I plug it in the router, the LED in it starts blinking (in normal usage, the LED becomes red for a couple of seconds, and then becomes steadly blue, when it gets connected into a equipment). It is probably a matter of power, as if the router wasn't providing enough power to it when it's plugged.Afterwards, I've made the following tests:
1) Used this External HDD in 3 different equipments (a notebook, a netbook and a TV), with different versions of USB ports. It was recognized and read normally in all of them.
2) I tested a pendrive with the router. After RESCAN, it was shown normally in Storage Sharing page.
3) I have downgraded the firmware to 120509 version, plugged the HDD in the router, and once again, it was an unsuccessful try.
What I can conclude from those tests is that:
1) My External HDD is working normally;
2) The router's USB port is working properly;
3) So, if both are working, it can only be a matter of compatibility between them.

Recently I replaced my Linksys WRT54G for a TP-Link WDR4300. But unfortunately this did not result in an increased speed.On both the 5GHz and 2.4GHz speed is limited to roughly 2.5-3 MByte/s, which is OK for watching movies etc. but I could reach those speeds with the 802.11g router as well!
I'm using the WDR4300 as access point, so I disabled DHCP server and NAT functionality, left the WAN port empty. And I set fixed IP in the subnet range of my modem/router. (horrible Speedtouch device). All works fine and stable, but too slow.
In the wireless settings I tried the 20 and 40MHz bandwith, disabled WMM, tried to lower the transmission power, tried to set a fixed channel. But all those changes do not have a significant influence on the transfer speed. (both on 2.4 and 5GHz) I'm the only 5GHz access point in my neighborhood, so interference cannot be a problem.
The clients indicate a link speed of 300mbps very close to the router, and this drops to indication of 54mbps further away, but effective link speed remains fairly constant (and stable!) (I find it strange that indicated link speed already drops at 3 meters with clear line of sight to the router)
I did the tests with fixed IPs on two laptops and no devices connected on the LAN ports, to rule out problems caused by the modem/router or other clients.The tests were done using a Lenovo x220 and Asus Zenbook, both with Intel dual band 802.11n wifi interfaces. The Lenovo reaches 22MByte/s via the Cisco access point at my work (with less signal as at home).

My DSL connection comes into our house in the basement and the DSL modem came with a router included. I bought the WDR4300 for the higher speed wireless connections and the gigabit ports. I really don't need the "router" functionality. I would like to put the WDR4300 on the second floor to give (hopefully) the broadest wireless range. However, I would like all my PCs (including those wirelessly connected) to be on the same sub-net. Is there a way to configure the WDR4300 so it acts like a switch rather than a router?

I'm having difficullty configuring a USB hard drive to my WDR3600
The WRD3600 is acting as a switch with my netgear cable modem router as the DHCP server. The DHCP server on the WRD3600 is turned off. the WRD3600 is accessible on my home network and I can connect to attached wifi and Ethernet devices.
when I attach my WD USB hard drive, I can see the device on the WDR3600 web GUI USB settings page. The WD hard drive service status is started and enabled. when I click on the open the disk link, nothing happens. When I try to access the 192.168.x.x/volume1 address, I get a page that says the username or password is incorrect.
When I disconnect the WDR3600 from the rest of my network and turn the DHCP server back on and connect directly to the router, i am able to access the connected usb hard drive.
is it possible to have the WDR3600 acting as a switch with DHCP server off and still access usb devices connected to it?
