Thanks a lot for testing and feedback, I really appreciate it. I found and downloaded the old DG834GT_V1.03.22_DGTeam_1014 at Rapidshare but it had the same problem as the Rev.1018. However the problem does not occur with the latest official Netgear firmware, DG834GT_V1.03.23, nor with the older DG834GT_V1.03.16. I will later test the official DG834GT_V1.03.22 to see if I get the same problem as with the DGTeam firmware since they are based on that version. Maybe the problem is due to a combination of the ADSL driver and the default ADSL settings given by my ISP (VPI=8, VCI=35).
