I've got a wireless router. Recently I found out that my mobile is having issues with the WiFi connection. I went through the settings and found out that there is an option in the router WiFi settings where I can select a band:

enter image description here

Now earlier it was set to 2.4 GHz (B+G+N). What is the best band that I should chose so that my mobile (Sony Xperia P) will get the best WiFi connection? And if any other settings you see are wrong please correct them! :)

Thank you.

Technically they are all the same band which would be 2.4GHz. As for the "best one" that depends on what your laptop supports. Check the specifications of the laptop to determine which version of the 802.11 standard your wireless adapater supports. Unless you have devices that only support 802.11B you shouldn't enable it since 802.11N wil slow down to the slowest client. –  Ramhound Jul 17 '13 at 13:40

I think the title of this question isn't really asking for what you want to know, is it? –  gronostaj Jul 17 '13 at 14:28

2,4 is the frequency, b/g/n is the standard, the "best" connection is guarranteed with n, because it is the newest standard. the IEEE standard is called 802.11n for example. it supports up to 150Mbit/s!

So I've got a N compatible device! That means the best option is to go with the N standard! is it! :) –  Dimal Chandrasiri Jul 17 '13 at 13:42

yes, if your wireless card supports it! –  MIC Jul 17 '13 at 13:44
    
please mark it as answer, if it helped you ;) –  MIC Jul 17 '13 at 14:00

Some additions to the other answers:

  • Channel Number: Since you are using an Android phone (Sony Xperia P), I suggest you install the WiFi Analyzer app from the Play Store. This will show you which Wi-Fi channels in your neighborhood are more heavily used and which less. Go everywhere where you expect to have connectivity (some neighbor networks may only be visible in your kitchen, e.g.). Change the Channel Number setting to the channel with fewest other visible networks, including channels close by (those Wi-Fi channels have some overlap).

  • Radio Power: Your setting is 60 mW. In most countries, 100 mW is the maximum allowed transmit power for 2.4 GHz Wi-Fi devices, as long as they do not use directed antennas. If you have problems with reception from the distance, you could try to increase this setting, if regulation allows it in your country. (Normally, the device should "know" and prevent you from setting an illegal value.)

  • Band: Although 802.11n is the fastest Wi-Fi substandard, it might not necessarily be the best for your combination of router and mobile phone. You should try 2.4 GHz (B+G), if your problem is with broken or intermittent connections. There are reports of broken 802.11n connectivity with certain software releases of the Xperia P. Edit: If this setting does not resolve your issues, you should chose 2.4 GHz (N), as this is the fastest setting. However, older devices than your mobile might not be able to connect at all with this setting, so choosing 2.4 (G+N) or even 2.4 (B+G+N) would enable older and oldest Wi-Fi devices to connect to your router.

Good luck!

ps: What is your Mode setting and what options has it? It is not visible in the screenshot.

@Ramhound I disagree. There are devices with known stability problems using 802.11n. A fallback to 11g or even 11b could show if this is the problem. Unfortunately, the questioner did not elaborate what "having issues" means for him, but a slow connection is only one of them, interrupted connections or inability to connect at all would be others. –  Dubu Jul 17 '13 at 15:26
    
I could agree supporting N+G wouldn't slow his network any other combination is just asking for network performance issues. –  Ramhound Jul 17 '13 at 15:28
    
I added some text explaining which would be the fastest and the most compatible settings. Maybe it's clearer now. –  Dubu Jul 17 '13 at 15:54
