My computer started getting slow, speeds lower than 2 Mbps at times & I pay for 10 Mbps. Additionally I would attempt to open my browser & get a message stating "page cannot be displayed", even though my router had all the lights on & blinking that should be & icon in bottom right corner of my monitor showed I had internet access. I have had tech support from my ISP provider for the last two days, inside my computer & outside of my home checking wires, etc. & they have been unable to find any problems. The tech that came today tested my DSL on his laptop & it worked great, hooked it up to my desktop & it the speed dropped dramatically. It was taking approx. 1000ms to ping! I am using IE11 & my OS is Windows 8.1 64 bit. I installed Windows updates and it seems that's when I started having problems, especially with Adobe Flash Player but read in their forum that Windows put out a security update, (KB3087916), for 32 bit operating systems that was causing problems with error messages, etc. I am getting those same error messages. But I was told by the tech that he had seen this same problem one other time & that partitions had somehow installed in the browser and behaved like a firewall & that would cause connectivity issues as well as speed issues like I am experiencing because there is no consistency to either issue, its totally random. So, if anyone has ever heard of this & can help me see if that is indeed my problem I would really appreciate it. Thank you!
