I am having problems with the Sagemcom 5355 modem. My PC wont connect to most sites and my gaming experience is poor. I have looked at a list on this forum however there are no "good" modems listed that have a WAN port. This is essential for my ISP (Telstra). My obvious question; is there a good modem that is compatible with Netduma that has a WAN port. Help would be appreciated as 12 months of pulling hair out has left me bald! Also i do not require WiFi. I apologies for the misspelling above...... obviously the hair loss is to blame.

When my PC is connected to the Netduma router web pages time out. The same does not happen with my laptop (when connected via cable). I have had the router for some time now and the problem has been happening for some 4 months. I was wondering whether settings on either PC or router or modem are incorrect. Also have noticed that whereas when I first got the router gaming (Destiny PVP) improved, now its probably the worst it has ever been. I have factory reset router and nothing has changed. I am at a total loss as to what to do. Even to get to this forum i had to disconnect from netduma router and connect to modem.
