Connection drops many times a day, Help please?

Question

I have a HP Compaq Presario CQ57 with microsoft windows 7 home premium, it has a realtek network adapter wifi and connects the the LAN but keeps dropping connection to the internet (yellow triangle with an exclamation mark inside in the tray)

I have tried for over a week fixing this connection but I can't get any luck.
I've taken these diagnostic checks for you all to see... Hope you can help, here's what I have in cmd

Many thanks in advance.

Answer 1

It looks like you're computer savvy so try changing the channel on your wireless router. Bleed over from other wireless networks in your area can easily disrupt your signal. Most wireless routers come out of the box set at channel 6 so try a different channel.



Awesome detail! Anything related to "Local Area Connection" in nbtstat and ipconfig will always be nothing since you're not hard wired. Ignore the annoying "tunnel" stuff.



Does your wireless router have any logs?



Respond back if it's too much geek speak or not enough. :D

Answer 2

It may be that your ISP is allocating a new IP address every day. This reduces the risk of becoming a zombie bot.

Answer 3

Try changing your DNS server to 8.8.8.8 or 8.8.4.4 which is Google's DNS. Additionaly you may need a stronger wifi adapter. I recommend
