Problem with internet connection speed
Problem with internet connection speed
You're experiencing a significant speed difference between your Lenovo g580 and ThinkPad T470 on Wi-Fi. The T470 is showing much lower download and upload speeds compared to the g580. It seems the issue might be related to outdated hardware or interference, even after rebooting. Since both devices are connected to the same network, consider checking for interference sources, updating firmware, or replacing the Wi-Fi chip if necessary. If the problem persists, replacing the chip could be a viable solution.
It's a Wireless N chip, likely single band. The main concern is that Lenovo tends to whitelist certain cards in its BIOS. If your card isn't on the list, the computer won't boot. It seems newer cards probably won't be included either. Using a modified BIOS could work, but that's risky. The G580 appears to be a budget model with only 10/100 Ethernet built-in. You might find adapters that fit this setup if you locate a compatible list. On another note, if you can locate the current WiFi card, inspect the connections to ensure they're firmly attached—maybe the antenna wires are loose.
Check the Device Manager for the exact model of the WiFi adapter on the G580. It appears to be a wireless-B/G/N adapter from an older generation. The T470 uses an Intel 8260 wireless-AC adapter. Identify your router or access point make and model. Also, note the ISP speeds you’re subscribed to.
Thanks for the advice! It seems BIOS hacking isn’t realistic for me since I’m still getting familiar with tech. I probably wouldn’t have understood much without some research on Wi-Fi basics and how it connects. I don’t use Ethernet, just a cloud device powered by cellular service. I’ll see if the WiFi card is secure. Appreciate the help!
The WiFi adapter for G580 is a Broadcom 802.11n Network Adapter. Since I don’t have a router, I’m using a 4G LTE cellular modem. I’m new to this, so if you’d like guidance, we can go step by step together. (I’ve attached a screenshot for reference.) You’re paying for 150Mbps, but with cellular devices like these, you’ll likely only get around 50Mbps at most, depending on nearby connections. (This info is listed on their website.) Please let me know if the screenshot contains details I shouldn’t share publicly. ^_^
When setting up a router, I usually specify the band name in the SSID. This helps me identify it. It might appear under network settings. Unfortunately, it's been quite some time since I used my Windows machine, so I'm not sure how to do this on Windows now. You might try logging into the router and checking for 5GHz details there. I see that mine lists connected devices per band, but I also have a high-end router.
