And replacing gear, redesigning the setup doesn't help it's time to get a pro in there.
It may be cheaper to replace the lone laptop with another. Remember I'm only working with your post and claims it's " the most complicated and unexplainable issue of the internet world. "
I've solved some hundreds over the years but let's go with what you claim here. It may be that the best solution is to swap that out. Again, I'm taking your word that you've reloaded and more.
Hi all.... Here I stand confronted with the most complicated and unexplainable issue of the internet world.
I have been using my Wi-Fi for years. I got a laptop, desktop, smart tv and mobile. Out of all the devices only the laptop shows the yellow triangle and No Internet Access on the wifi signal bar with full signal available. The desktop, mobile and smart TV do not show the yellow triangle and work fine. I have been facing this problem with laptop only for the last 10 days. Before that it was working alright.
The more surprising element is that this very laptop works perfectly when used with another Wi-Fi, and even more surprising than this is the fact that this laptop loses the yellow triangle and works fine when there is a power breakdown and the Wi-Fi is supplied with a UPS power. (We repeatedly have power breakdowns and use a UPS to cover up). So the laptop has the yellow triangle when the wifi is used with electricity provided by govt and no yellow triangle when wifi used with UPS. The other devices work ok when wifi turned on with govt electricity or UPS.
My laptop is run with Windows 7 32 bits and there is nothing "unusual" installed. I have only MS Office, Yahoo messenger and Skype installed in addition to the build-in hardware/software.
I have been searching the internet to resolve the issue by visiting various forums. In fact nobody has posted an issue exactly the same as mine, but still I followed the solutions given by experts on the net issues somewhat similar to mine but nothing works.
I am at loss thinking about all this. If the modem/wifi/net connection has any problem, why do all the other devices work ok? If my laptop setting has any problem, why it works ok with UPS or with a different wifi?
I turned on/off wifi repeatedly with long gap.
I disabled/enabled internet connection.
I did config/release config/renew
I connected the laptop directly to the modem with a cable but still the yellow triangle there.
I restored my computer setting to an older time when it was working alright.
I thought of having a new windows done but didn't think it would work as it already works with this window on a different wifi or current wifi with UPS.
What else would anyone suggest to resolve the problem??
