Hey everyone, I'm facing an unusual problem with my 5G Wi-Fi setup after installing a 3070TI. Previously, I had an EVGA branded 1070TI that performed perfectly without any issues for years. Recently, I switched to an MSI Ventus 3070TI and it initially worked well. However, over time the connection started to fail—once it would connect right away at startup, but later required rebooting the router for 5G to function, and even then the connection appeared as a hidden network on the PC. Despite my phone being connected nearby, I couldn't establish a stable link.
I've tried everything: using my original Wi-Fi card, an old sub-dongle, a USB hub with a 3-foot extension, and even replacing it with another dongle. Nothing resolved the issue. Recently, I removed the 3070TI and reinstalled the 1070TI, which suddenly fixed the problem—5G appeared and connected instantly.
I'm currently building a new system from scratch with all fresh components and power supplies. After combining the 1070TI with the 3070TI, the 5G connection worked smoothly on my built-in Wi-Fi, with the dongle, and even with the old card. However, once I swapped back to the 3070TI, the 5G disappeared entirely. It doesn't connect through onboard Wi-Fi, USB dongles, or the old card.
Has anyone experienced this before? Could interference be blocking the 5G signal on my computer? This is puzzling and I'm not sure what's causing it.
I've reinstalled both network and graphics drivers. The new machine I built came with the latest BIOS on its motherboard. The previous one functioned temporarily before gradually failing over three weeks, with no other changes to the system—no updates, not even a Windows patch during that period. It's likely the BIOS was the problem from the start, especially since the new graphics card didn't prevent it.
I think the antennas are located at the rear of the computer. You might consider using a cable to relocate them from behind to the front, keeping them clear of obstructions. Of course, if interference is the issue, it could originate inside the PC, but generally having an antenna positioned this way improves reception, so I always recommend it.
I tried connecting a USB Wi-Fi dongle using an Asus model with a 3-foot cable hub. Plugging it directly into the case or the hub worked similarly; both showed a 2.4G connection but blocked any 5G signal. I later considered using an old antenna setup to extend the connection further from the motherboard or Wi-Fi card. I'll test that approach and check the outcomes. Edit2: Longer antenna cables didn't help...
It's odd considering the hidden network aspect, though I figured it was worth a shot.
