I have Comcast 768K/6M package, but my upload speed can only reach 400 Kbps.
The Comcast technicians came several times, they changed the cable line, adjust the signal strength,
the upload speed indeed increased........ from 200 Kbps -> 400 Kbps............. still far away from 768 Kbps.
The technician also tried to use their own laptop, same speed. They also confirmed the cap settings are correctly set to 768K/6M.
There are no viruses, no spywares.
After their adjustment, the ping value decreased from 400 ms -> 50 ms.............. it's good, but the speed still under 400 Kbps.
They've tried to solve the problem for several weeks,, still can not figure out how to solve this.
Anyone can help??? Thanks.
