Hello, I purchased a fresh Switch—a D-Link DGS-108GL with 8x1Gbps RJ45 ports that are unmanaged. My goal is to connect the internet from the Switch to my PC room, which already has two UTP Cat5e cables running through the walls from the Switch area and also to a future room. I plan to use the same cables for both setups.
The problem started when I connected the internet via the Switch as shown in the first image. Internet connectivity became unstable. On YouTube, I can handle buffering well, but Steam often drops, Discord voice calls lag, and launching Discord takes a long time. In Windows, the connection sometimes shows as no internet. The cables through the walls seem fine.
I tested with a cable tester two days ago when a friend working for an ISP helped me install new RJ45 jacks for the newer B standard, since all were using the older A standard. I haven’t checked the cables used for bridging from the modem to the Switch yet, but one of them has worked well for some time before I moved in. I also have a spare cable that behaves similarly.
If I connect the internet directly to any wall port without the Switch, it works perfectly. Both RED and GREEN ports function correctly when routed straight, though they have issues when passed through the Switch. However, using my old 100Mbps switch with the same cables and setup resolves the problem completely.
I attempted setting a static IP for my PC, but that didn’t fix it. I increased the buffer settings on my PC’s NIC to 2048 and switched to FullDuplex 1.0Gbps, but neither helped. I’m unsure what’s causing the issue anymore. Anyone has any suggestions? I’m willing to return the new switch and stick with the older 100Mbps model since it works reliably, even though it’s much slower. I’m using Cat5e cables.
It seems the setup changes are affecting how the system responds. Using the original switch versus the new one might influence stability, and adding a switch between UPS and PC could stabilize the connection. The difference likely comes from how power routing and load balancing work in each configuration.
they say it supports 1Gbps though... but thank you nonetheless. Also, i plan to place a UPS between the modem as you recommended, but i took it out today since it was making noise in my bedroom and the LED wouldn't turn off. i'm going to return it and see if another works better. The one next to my pc is completely silent but sadly too costly to replace just for a modem either.
@Hairless Monkey Boy @AbydosOne just to avoid creating another topic... if I have a UPS with an RJ45 data line protection, can I connect an RJ11 into it for the DSL modem? I've seen that an RJ11 works with RJ45 (it's narrower now, using 4 pins instead of 8).
