I have been experiencing some sluggish performance now for about 2 weeks with my DSL broadband connection. For instance, I can not playback any online multimedia clip without it pausing for several seconds and then resuming to play. It is almost like the connection is constantly rebuffering throughout any playback of an online movie clip no matter the length of its duration.
With respect to my setup, I have a Westell DSL modem which interfaces with my Netgear Wireless N Router. The OS on this computer is Windows XP Pro SP3.
In terms of troubleshooting, here is what I have tried so far. First, I tried just a direct connection between the DSL Westell Modem and the pc, thus, taking the Netgear Wireless N router out of the equation all together. The problem with the movie clips freezing up and resuming playback still occurred. Secondly, I carried out the latest firmware update for the router which installed successfully. Thirdly, I downloaded and installed the latest of CCleaner; removed unnecessary file. And, finally, I installed and downloaded the latest version of Malwarebytes. When I ran it, the test came back clean and free of malware.
In closing, if anyone has any suggestions in terms of what I can do next, it will be greatly appreciated. Most likely I will need to contact AT&T and have the DSL modem replaced because it is an older unit. I have not checked on any firmware update for this modem because I was not quite sure how to do it. With the router, the firmware update was easy to do because it automatically alerted me to do it.
At any rate, if someone could provide some suggestions I might have overlooked in troubleshooting this problem, it will be deeply appreciated. I look forward to hearing back from everyone regarding this question.
If more information is needed, please feel free to let me know and I will post back accordingly.
