I face the same issue, i have upgraded the firware and tried with soft and hard resets but wifi behaviour is wierd. It finds wifi networks sometimes and sometimes doesnt and when i try to enter the pre shared key and connect it says unable to connect?

If its a a common problem with E71 nokia phones, as i have seen many users facing the same issue then why Nokia doesnt release the fix

Please help

First of all, turn off the power saving in the advanced settings of WLAN from your phone. Don't use IPv4 config, set it to automatic (DHCP). Set the router or AP to WPA-PSK/WPA2-PSK and fill in the passfrase of 13 digits. Turn off the WPA2 only mode in the phone and use the Pre-shared Key (PSK) from the router or AP.

[xiarahman]

where can i find the power saving option. Can you please guide me on my E71.

Thanks!

Menu-> tools-> settings-> connection-> Wireless LAN-> options-> advanced settings-> yes-> power saving-> disabled.

[xiarahman]

Yeah i tried disabling the power saving option but its still the same. One thing i have noticed is when i switch the phone in offline mode it detects the wireless network 100% and when i try to connect providing the pre shared key it gives the same message "Wlan: unable to connect: Wlan network not found". But in online mode it rarely detects the network even. Please help me

[hadimassa]

Are you sure the SSID of the router is set to visible?

[xiarahman]

Yes the SSID is set to visible and there is no filtering of MAC on the router.

Have you already tried changing the WLAN channel that your access point (or router) operates on?

You could try configuring your WLAN access point to different channel to see if that helps (try few different channels). In case you have plenty other WLAN networks (from neighbours) operating on the same channel than your own WLAN network it can cause interference for your network. Sometimes interference may also be caused by non-WLAN devices operating on the 2.4GHz frequency band, most common sources of interference (for 2.4GHz 802.11b/g WLAN) are cordless DECT phones and Bluetooth devices.

Have you tried switching your WLAN access point configuration between different security modes like WPA2-PSK (AES) and WPA-PSK (TKIP)?

Also check if there are firmware/software upgrades available for your WLAN access point model making sure you're running the latest access point firmware version. Try performing a factory reset on the WLAN access point configuration (if you know how to re-configure your WLAN access point).

[xiarahman]

I have tried soft reset, hard reset (factory reset) , upgraded the firmware to the latest version - tried even changing the security modes, and channels on access point  but all invain.

The thing is why doesnt it detect the network when the phone is in online mode ?

I wish someone from Nokia support helps me out.

[hadimassa]

When you open the conn.mgr.-> available WLAN networks, do you see your network? If you do, define the accesspoint in options. If you don't, go to a friend or free hotspot to check your phone. When you can make a connection there, your router is the problem.

Problem? What problem?

[tomasvaril]

Same To me. I have Asus WL-500W router at home, WPA2-PSK(AES), password similar to this "lIGf@91pY0TnFY!Jh@7LjTUlsL3ZPY", MAC address filtering. My old Nokia E51 works, my Touch Pro Works with it. When i try my one day old Nokia E72 it does not work, the same like others:WLAN: Unable to connect. Wlan Network not Found. E72 works at my work wifi, which has the same settings but without mac filtering. Have no idea what is happening, all is setting correctly. MAC address of E72 is allowed on router. It has the same settings like E51, but E51 works like a charm E72 does not work. What is wrong?

Try to set the WPA2 only mode off and turn off MAC filtering just to check.

As already suggested, you could try disabling the MAC filtering from the router, just to outrule possibility of a typo while entering E72's MAC address to router settings.

Have you tried swithing a WLAN channel that your router uses?

Log in to your router's web management pages (check router's default IP address and username/password from it's manual) and switch of the "Automatic" channel selection mode. Try few different channels, like 1, 3, 6, 9, 11, if one of the channels happens to work any better. Note that in case you have set your router to use channels 12 or 13 (or in case "Automatic" channel selection mode has decided to select channel 12 or 13) you must have a SIM card inserted and some other than "Offline" profile enabled on your phone since Offline mode (i.e. airplane / flight mode) won't allow your phone to operate on higher channels than 11.

In case you have configured your WLAN network (SSID) to be "hidden", try disabling hidden SSID mode on the router.

Asus WL-500W router seems to be a pre-standard 802.11n device so might be worth looking in to your router's WLAN settings and see if playing around with router's WLAN operating mode and settings improve the situation. First of all ensure that your router is not set to operate in 20/40MHz mode (set it to 20MHz only) assuming that the router is in default 802.11b/g/n mode. You could also try disabling the 802.11n mode completely by selecting a 802.11b/g mode (if available).

You should probably also check that you're running latest (2.0.0.6 ??) firmware version on your Asus WL-500W router since there seems to plenty of complaints regarding WLAN connectivity and stability issues (in general, not specific to Nokia handsets) with this particular router model.

[tomasvaril]

Thank you guys for help. I have just changed only channel from Auto mode to channel number 6 on router and phone has sucesfuly connected to AP. It is strange than old Nokia E51 has no problem with connecting to AP and brand new Nokia E72 has one :-) Thank you again fo help!

[herrfox]

also fo NOKIA N8 THE SAME PROBLEM: Unable to connect - WLAN Network not found;I see my network in the wlan list but when i try to connect to it,i read: Unable to connect-wlan network not found;i tryed with: mac filter on/off,dhcp on/of,wep protection on/off,firewall router on/off,power saving in the phone on/off, but the problem is the same ever!..Niklas Savander,..where you are?..nokia is back?..but with the same problems!

[tomasvaril]

Have you tried to set channel of your WiFi router for example to 6?
