I just bought a new ADSL2+ modem today-D-link DSL2542B.
My ADSL line(Streamyx) quality is not good because of the bad copper connecting between the cabinet and DSLAM.Thus,the free modem given by TM-Billion 5112S can’t get a stable connection always.I googled a lot to dig out how to get a low line attenuation and high SNR margin to achieve a much steady online experience and I found that the modems which are built with Broadcom chipset normally could gain a good result on a bad condition.That’s the reason why I choose this modem.
I have to say that it does work well at current condition.Here’s the ADSL information from the modem:
The downstream SNR margin shows consistently at 28-29db whereas the downstream line attenuation becomes at 43.5db,slightly lower than before.

The TM technician who I’m familiar with is still looking for a way to let me have a better line attenuation in order to fulfill the requirements applying to upgrade to 4Mbps.I wish that will be a way indeed.
Through doing the settings and testing,I met some questions and didn’t solve yet.
- I can’t get it work once I set this modem at bridge mode connecting with Linksys WRT54GL router.
- It seems like only auto connection could be done in the modem.I can’t manually connect or disconnect one session.
Anybody has solutions?
