Im trying to setup my wireless router I've had for a while to have a password.It has been unsecured since I've had it.I have the manual but not the install wizard.I tried probably a hundred times but cant seen to get it right.The model is F5D7230-4.I called the support number but they dont offer complimentary help anymore.The router works excellent but I just cant get the security password to setup.I reset it a few times and tried and tried with user manual directions but I must be stupid or something is wrong.Please help.Thanks.
