Region : UnitedKingdom

Model : TL-WDR3600

Hardware Version :

Firmware Version : 3.13.23 Build 120820 Rel.73549n

ISP : Virgin Media

Hardware version: WDR3600 v1 00000000

NB: Wired connections to the router work fine.

I'm having problems with the wire less connections to my new router. The following problems occur with a range of devices (mobile phones, tablets, game consoles, laptops; so we're talking WiiOS, Win7, Android Jellybean and Gingerbread, Win7 Mobile). The issues do not seem to be linked to a particular device, with any device having problems when another does not.

1) Device does not see WLAP AP SSID
2) Device connects to WLAN AP, can connect to TL-WDR3600 management web interface cannot connect to internet
3) Device connects to WLAN AP, but cannot connect to anything
4) WLAN AP SSID intermittently dissappears from scan list

These are not isolated issues (i.e. I don't only experience one of them at any one time).
eg. A device can connect, allow me to browse one page, then the AP can dissappear

Rebooting the device, toggling WiFi, rescanning / reconnecting does not seem to help.

One device can be experiencing one of the problems above, whilst a second device physically adjacent (eg. two mobile phones) is having problems.

The problem occurs when the device in running combined 2.4/5G, or either band individually.

I've changed many of the Wireless settings in an attempt to isolate a cause, but have not been able to determine what the problem is, including factory reset and reconfiguration.

I'm using WPA2-PSK. My previous router (D-Link DIR-615 with horrendous Virgin Media firmware) was working fine with the same in-house devices (known issues with pre-loaded VM firmware aside), and I am sorely tempted to return to that router since at least I can get devices running on the internet.

I can't see any newer firmware available on the website.

To summarise:
Wired connections are fine
Wireless connections are largely useless (fail to operate 90% of the time I try to use them)

Any clues?

Best regards and Happy XMas
