Greetings.
I am currently trying to troubleshoot slow web speeds on our clients. We have IPS, Proxy and most other stuff disabled, no QOS activated - however, download speeds from *any* website are 3-5 MB/s tops. Multiple parallel downloads on the same client are possible, each showing the same speed of 3-5 MB/s. Our Lines are 200/200 and 50/10 as Backup.
So I read on the kb and forums about some basic settings to look into, one of them being the Interface Link Speed set under Interfaces, Hardware Tab. We have all set to auto. I tried to set the main uplink to 1000BaseT/Full. Once saved, both uplink interfaces will show "Link: Down, Status: Up". I tried reboot, I tried setting back to Auto, I tried to renew connections. PPPoE Log will show that there is no feedback from the ISP on these interfaces. 1000BT/F should work, as all devices in the chain are able to handle GB speeds.
Now there are two funny observations:
1) No matter what link mode I set the interfaces to, I cannot establish uplinks anymore.
2) I was only able to reestablish uplinks by recovering the config backup I made prior changes.
3) Even with those backups, it took me a couple of tries restoring and rebooting the SG135w. For the first couple of tries, Interfaces were stuck in "Link: Down, Status: Up". Then they were showing both as Down, and finally we went back to normal.
Has anyone a test environment available to tryi it? The backup line is using a ZyxelYMG1312 (10/100 Link Speed), and the main line a Genexis Box (1000).
