Re: Is someone stealing my wifi?
To log into the router, enter the URL 192.168.1.1 (not in the Google search box)
You should be presented with a window to enter the username and password.
For the Username type admin tab down to the next box for Password and type password then login.
Both are case sensitive. I can't find any manuals for the Westell router and on their site which had dead links, informed that these routers had been sold to Netgear and for any support regarding the router, you had to contact your ISP Verizon.
WEP is quite an old security and so I've read, can be easily cracked. There may be provision to upgrade this from within the router to WPA/WPA2 but some older routers can only connect on WEP.
You will need to contact your ISP about this.
As I'm unable to locate any link for a manual for your Westell router, you'll just have to feel your way around for the DHCP Table once you've logged into it.
