Lets do some basic IP (Internet Protocol) Network checks first............which is the underlying network protocol for Web browsing.

(1) Is your computer set for dynamic IP address allocation - DHCP or static IP...check via the network connection and TCP/IP properties tab.....should be DHCP ideally

(2) Does your computer get allocated an IP address ok ? - check by Start - Run - ipconfig/all (win2k/XP)... or winipcfg (Win98 )......this is a part of windows "Windows IP Configuration" and will tell you if its communicating okay with the router. You should have the IP address, Subnet mask and default gateway fields all populated.

(3) Assuming all the above are okay can you ping the router "Start - Run - command"....this will open a DOS shell window for your - white on black.......just issue the command "ping ip_address" where Ip_address is the default-gateway (router) IP address - dotted decimal series of numbers. You should get a "Reply in X ms" if all is well

(4) Post the results to help the diagnosis be completed.then try a "tracert www.dell.com" to see if basic Ip connectivity and DNS (Domain Name Server) are working correctly from the DOS window.

Run-time error '91': Object variable or With block variable not set.

That error is associated with the Visual Basic runtime system, according to this article.

It's very odd to be getting an error like that inside Internet Explorer, unless there's some extension that's using Visual Basic.

In addition to sentinel-master's suggestions, you may want to try disabling third-party browser extensions under Tools/Internet Options/Advanced/Browsing, and restarting Internet Explorer. If the problem disappears, there's a possibility that the error is caused by spyware or malware.
