Hi All! I recently purchased a Cisco 3750x from ebay to replace my dead Cisco 2960G switch. After resetting the switch to factory default settings and some basic configuration, I'm only able to receive no more than 300/300 with a 1000/1000 AT&T Fiber connection.
When the 2960G was operational, I was able to achieve 800/800 and sometimes more. I do have an ASUS AX58U router behind the switch however, I have eliminated that as the culprit after hooking it directly to the AT&T gateway via cat6 cabling and achieving ~800/800 speeds. Also, speed tests from the gateway itself show 950/950 (of course from AT&T servers).
Just curious if there is a configuration issue or something I might have missed on the 3750x that would possibly prevent me from achieving these speeds. I've attached the config of the switch. If someone with a bit more experience could just do a once-over on my config to see if I messed something up.
Connectivity is as follows
Fiber to ONT <CAT6> ATT GATEWAY <CAT5e> ASUS ROUTER <CAT5e> Cisco3750 gi1/0/5
If any other information is needed please let me know, thank you for your help everyone!!!!
