Hi,
I have my RUT240 set up as a modem using IP Passthrough. This has worked fine for some time, but just recently I have started to experience difficulties loading certain web sites after the RUT has been active for some time. Restarting the RUT solves the issue for a couple of hours. When this happens I can still ping the URL, so it is not a DNS issue. Restarting the router behind the RUT does not make any difference. All devices on the network show the same problem until the RUT has been restarted. It seems that it is only affecting some web sites and not necessarily all at the same time. One example is www.canyon.com. If I disable WiFi on my phone and try the same URL using the phone's 4G instead of the RUT the site works well. Operator is Telenor, and I am using APN internet.telenor.se.
Any ideas?
