Static dhcp ip is given by the isp, that's how they allocate the ip's to their clients, don't know why... Signal strength is around 80%. I tried the following last afternoon: ping my router with 6400 bytes, 0% loss, average ttl = 3ms. Tried to ping my access point, any packets bigger than 1024 are dropped and "request timed out" shows up. That led me to believe that the problem lies with my access point. Am I right? Funny enough, this setup worked flawlessly until a few days ago. Rang the isp and told them about the problem (the access point is theirs) and they said will come to replace it. Will see if after replacing it I'll have the same problem and will come back here to let you know. @Tain Thank you for your help. I haven't used any tweaks, any new firmware, everything is exactly as it was when it was working.
