Hello,

With 40MHz, primary channel 11 + Lower is not possible, only Upper is possible which means channel 7 for the secondary (extension).

Lower or Upper means the primary is lower or upper than the secondary (secondary = primary + 4 for Lower, or secondary = primary - 4 for Upper)...

All right. Why then have no problem to connect with my phone galaxy s2 ?

Why can’t I connect to a network?

A lot of variables are involved when you connect to a network: cables, network adapters, drivers and routers. So troubleshooting network connection problems can be challenging. This article can help you find and fix problems with wired (Ethernet) and wireless (WiFi) network connections. Some common problems are:


A wireless network adapter switch is turned off


Flight mode is turned on


Disconnected or improperly connected cables


Incorrect WEP, WPA or WPA2 security keys or passphrases


Mismatched wireless standards


Missing updates


Incorrect network connection settings


Damaged or incompatible drivers


Hardware or software problems

You have no problem with your Galaxy because either your router uses a wrong denomination (lower instead of upper), or your Galaxy works only with one channel...

By the way, why are you screaming?

I can not believe that ddwrt have some problems. I want to read official answer from TP-LINK?
What they thing? I set my router to use low and upper but still no any luck.

I send many messages for support. At this time support is zero. Not any answers.
Other problem that I notice is that wifi randomly drop when I use intensively.

For that reason I will never buy from TP-LINK.

I do not understate why driver for Windows 8 x64 is still BETA?
Where is chef of TP-LINK wifi LABORATORY and testing?

This adapter can not work correct with W8 x64.

Where is Utility client for Windows 8 x64 for tplink adapter. Not have at all. Why?
Why this adapter not have certificate for full support of Windows 8?

Please tplink fix this problems. I agree to pay more but to have item/goods that work.

See what happens in a hot topic. TP-LINK indirectly blaming ddwrt in staggering incompetence.

Finally, who is to blame?
DDWRT or TPLINK?

Apparently I never have to find out soon if any of ddwrt not protect him self.

May be must blame this dude
