WIKI එක බලපන්/youtube එකෙත් ඇති upload ගොඩක් වැඩි කලාම SNR එක අඩු වෙනවා එතකොට සැරින් සැරේ disconnect වෙන්න ගන්නවා stable නෑ.SNR = signal / noise (adsl router එකට ලොග් වෙලා බලපන්)6dB or below SNR is bad, you will experience no sync, or intermittent sync problems7dB-10dB is fair but does not leave much room for variation in conditions11dB-20dB is good with little or no sync problems (if no large variation)20dB-28dB is excellent29dB or above is outstandingDSL, cable, and fiber connections need to be divided into different streams for download and upload, and since they all have limits on how much information you can pack into them, privileging download over upload is usually better.Most DSL is ADSL, where the “A” stands for “Asymmetric,” so the disparity is pretty much baked into the standard. There’s not much room for more bandwidth in copper wires, so keeping the lines biased toward download is probably for the best.</blockquote>
