josephsieh Posted April 18, 2005 CID Share Posted April 18, 2005 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???

DaveMan Posted April 19, 2005 CID Share Posted April 19, 2005 I have noticed that upload tests are much slower with Mozilla Firefox, but when I test with Internet Explorer this is what I get: :::..

DaveMan Posted April 19, 2005 CID Share Posted April 19, 2005 And one more thing I saw that you are using a Motorola SB2100. Call Comcast and ask them to get you the SB5120, thats then new out right now, that should help. Your modem might be old, give it a try.

DaveMan Posted April 21, 2005 CID Share Posted April 21, 2005 your definetely wrong buddy, the sb5100 is the new surfboard out right now, <snip>? Actually, I just called Comcast right now, and the tech told me the newest modem is the SB5120, I'm not trying to argue or anything but if u dont beleive me call them and ask. One more thing, he said it depends on your area, probably they only give the SB5100 in your area. Quote Link to comment Share on other sites More sharing options...
