Morning all,

I recently installed a different modem at home to run my Internet. I used to have a zyxel modem but it stopped working following very bad thunderstorms. Last night I installed a 5102g modem and connected to the Internet successfully on my desktop via an Ethernet cable as well as on my laptop via wifi. I cannot however, connect to the modem/router on my iPhone, iPad and my wife's Samsung s2.

I have been troubleshooting via suggestions on various forums such as resetting the modem/router, resetting network settings on my phone, switching it on and off, hard reset, etc. but to no avail.

What could the problem possibly be? Is it settings on my wireless devices or on my modem?

Please help.

Thanks in advance.
 
Is it an ADSL modem? Is your isp username+password saved in the router or are you signing in on the computers each time?
 
Strangely enough it doesn't work. Not even on my laptop when I switch the password off. It just says that, before I try to connect on my laptop, that he information will be shared with others. On my other mobile devices I cannot connect at all - password or not.
 
With some connections I've had to 'forget' the connection an then reconnect to get it to work.
 
Are you pehaps using the same ssid that you did on your previous modem? Maybe the devices are having trouble picking it up as a new modem and maybe the old saved network has to be deleted first?

All you need to do is open the wireless settings on the modem, change you Broadcast AP name to something different and save the settings. Restart your ADSL modem and connect. Or you can leave it as it is and delete the previous settings from iPhone, iPad and your wife's Samsung s2.
 
I did a hard reset on my phone and also did a reset on my network configurations I.e. "settings, general, reset, reset network settings" on my phone as well. It picks up the WLAN but when I enter the password, it dismisses it as 'unable to join'

When I remove the password from the modem I still canno join.
 
Redo your wireless settings on your modem. Change SSID to something else, set the security on WPA-2 , use your Cell number as your password, save or apply settings. Restart modem . If you cannot connect after that then Modem WiFi is faulty
 
If the modem is faulty, the surely I wouldn't connect via wifi at all? However, I can still connect via my wifi on my laptop. The only other option instead of wpa is wep 64 and 128 bit. I understand that that encryption is not secure as it can be cracked.

I'll try that way, but how do I set up a password on wep?

afaik the password can only have numbers and the letters a - f in it but I cant remember how long it has to be. Normally the modem will tell you it's too short or too long etc. when you try to save it.

Still, if its not even working with the security off then I doubt wep is gonna work either, but might as well give it a go. I think there might be something wrong with the router or some serious compatibility issues between the chipsets in the modem and the mobile devices. Maybe you can try updating the modems firmware?

edit: dont forget to change the ssid as well, that might work.

Hi there,
On some routers with wireless I find you need to put the MAC address of the device you are trying to connect with into the permissions table in the modem.
Have a look at doing that and see if the issues resolves itself.

In your router security settings, set your network authentication type to wpa2/wpa-psk
