I use the desktop via LAN (network cable) and the laptop via wireless. at any point in time i dont use both (pc and laptop) together. i have a Teracom type 2 modem. T2-B-Gawv1.4U10Y-BI.

so you are getting good speeds on the wireless network but bad speeds on ethernet based connection? this does not make much sense. wired connectivity should provide a better experience no matter how slow the overall speed is. what dns servers are you using on both the machines? (this should not be a problem though)how are the pings to google.com from both the machines?

SNR downstream --5.70 db on PC *** 18.60 db on laptopSNR upstream --- 32.5 db on PC *** 32.5 on laptop o_OThat doesn't make any sense as, whether you are using WiFi or non-Wifi SNR won't vary, as it depends on the phone line. Check your Lan cable.

Mind sharing from where you got this value ?

Ok, streaming is poor in desktop. Are you able to browse ? What about downloads and torrents ? Was that like this from the beginning ? Where you ever able to browse properly on desktop after getting this modem ? If yes, any particular incident after which this started ?


1. Try another LAN port in modem and check.

2. Changing the ethernet cable is an option. Hope you already tried that (confirm you used a new cable and not an already used spare cable).

3. Ping LAN card and see if you can get any response. Try updating the driver or borrow LAN card from a friend (compatible to your motherboard) and check.

4. Hardware reset the modem and check.

More on feedback.
