I have a westell versalink and when i log in it gives the speed 1792/448 but when ever I do a speed test like on dslreports I get like 641k/373 my upload is ok, just the download is real low, ive tried the cablenut tweaks and it not improving, Im guessing it has to do with Service Pack 2 because all our computers has it and all get around 600k on speed test even with the other computers turned off. I had my ISP run the test and they say the line is ok. Restarting didnt help.
