RTL8723BR bgn wireless LAN does not show the wireless n mode on my laptop.

RTL8723BR bgn wireless LAN does not show the wireless n mode ib the properties list under configuration, on my laptop. Tried updating OS updates, chipset drivers, wireless LAN adapter driver from HP site and also from Realtek site. No use. Looks like something else needs to be enabled or so to enable the wireless "n" mode on the adapter. It works fine in b & g mode.

Router supports "n" mode but can't select that mode on the laptop. Hence tied up with the "b&g" mode. To me, it looks like a problem on the laptop side only because no matter if the router is there or not the adapter on the laptop should show all the modes, that the manufacturer says it supports, as available. Appreciate a solution please

Sorry, typo in the name of the adapter. It is RTL8723BE bgn adapter  ( not RTL8723BR) Apologies on the mistake.

Hi:

I don't quite understand the problem.

The wifi card with the default advanced settings should have a maximum throughput (connection speed) of 72 MBPS on the 2.4 GHz wifi band.

That is wireless N speed.  Anything over 54 MBPS throughput is wireless N.

If you mean that you cannot connect to the 5.0 GHz wifi band, you cannot do that with the RTL8723BE bgn adapter, because that model adapter only works on the 2.4 GHz wireless band.

Hello Paul, Thank you very much for the prompt response. Really appreciate that.

In the advanced tab under the configuration properties of the adapter, thereis an option called "wireless mode". The drop down for that option shows only 3 options. 802.11b, 802.11g & 802.11b/g. There is nothing like 802.11n or 802.11a or ac shown there. I was wondering when the manufacturer says it supports 802.11n , should not that be an option in the list for the user to select that ?

But what you said seems correct. Currently it is working only on the 2.4GHz band with the 802.11b/g mode selected. It does not even show the 5GHz Wifi name  in the Wifi selection as well. So, it looks like it is not recognizing the 5GHz Wifi at all.

Your advise is much appreciated please.

Thank you.

You're very welcome.

I have an Intel 7265 AC dual band wifi adapter, and mine has no 'n' setting either.

That is normal.

Mine does have an ac setting because it is an AC card but it is listed under a separate heading.

Here is a screenshot of my adapter's advanced setting...same as yours, except there is an 'a' setting because the 7265 is a dual band wifi card and the 'a' means it can transmit and receive on the 5.0 GHz wifi band,

 As I posted earlier today, your card should be showing a connection speed in excess of 54 MBPS, which means it is operating at the wireless N speed.

See this screenshot.  You should be seeing 72 MBPS where mine shows 866.7 MBPS (because it is a 2 x 2 AC) card.

Perfect. That is a lot of information. Thanks Paul. Clears the queries as well. You have been really helpful.
