I am using WAG54G as I mentioned; I have serious problems. I am a user from Turkiye. I know my cables are just fine! No problems with them. Let me write down my problems and wait answers from you; 1. I am using the firmware 1.02.1. Which one is stable? I wonder if I can find the original one.. 2. If I only use the wireless there is no problem but when I connect a device with LAN ports the problem starts. I cant use 100mbps speed even when I connect the cable there is no light start to turn on on the front of the modem. When I reduce the speed to 10mbps it starts to work and the light goes on in front. What is the problem? 3. After dropping the speed to 10mbps and start using both wireless and cable connection after a time passes and this is nearly 30minutes. The connection drops , the internet goes down and I cant connect to any site or the modem but there is no change about the lights in front they are all green. I cant get into internet again if I wont restart the modem. 4. There wasnt anyproblems like these with the original firmware all of these started with the firmware upgrade. How can I find the original? 5. If the updates going to make is worse why do they make new firmwares? Thanks for your interest and taking time.
