The user is experiencing inconsistent network performance, with speeds fluctuating between fast and very slow without a clear trigger. This unpredictability is impacting their ability to use the connection reliably.

Web pages crawl, downloads fail.
The network, either within your home or at your ISP's level, is overloaded with traffic, leading to slower speeds for all users. This is common during peak usage hours.
An aging, malfunctioning, or improperly configured router or modem can cause intermittent performance problems. Overheating or firmware bugs can also contribute.
Wireless interference from other electronic devices or a weak Wi-Fi signal can lead to inconsistent and slow speeds. Obstructions like walls can also degrade signal quality.
Your Internet Service Provider might be intentionally slowing down your connection (throttling) due to data caps or network maintenance. There could also be issues with their infrastructure.
🤖 AI Analysis
"The user describes intermittent 'all over the place' performance, which is a classic symptom that a simple reboot of network equipment can often resolve by clearing temporary glitches and re-establishing stable connections. This is a quick and easy first step."
🤖 AI Analysis
"The problem is intermittent and affects all devices, suggesting a potential issue outside the user's immediate control. Contacting the ISP is crucial to rule out external factors like line issues, outages, or ISP-side throttling, especially since the user has a cable connection which can be susceptible to neighborhood congestion."
🤖 AI Analysis
"The intermittent nature of the problem makes it difficult to diagnose. Running speed tests at different times will provide concrete data to identify patterns of slowness and to present to the ISP, strengthening the case for an external issue."
🤖 AI Analysis
"The user experiences slow performance and failing downloads, which can be indicative of insufficient bandwidth, especially if there are multiple devices or heavy usage patterns. While they haven't recently changed plans, their current plan might simply be inadequate for their needs, leading to intermittent issues."
🤖 AI Analysis
"Cable internet plans often have data caps. Exceeding these caps can lead to throttling, which would manifest as intermittent and unpredictable slow performance. Checking data usage is a necessary step to rule this out."
🤖 AI Analysis
"Outdated router firmware can cause performance issues and instability. While not as immediate a fix as a reboot, ensuring the firmware is up-to-date is a standard troubleshooting step for network problems."
🤖 AI Analysis
"If the network equipment is old, it might not be able to handle current internet speeds or network demands, leading to intermittent performance. This is a more involved solution but relevant if other steps fail."
🤖 AI Analysis
"Wi-Fi congestion can cause intermittent slowdowns, especially if the router is on a crowded channel. This is more relevant if the user primarily uses Wi-Fi, but since the problem affects all devices, it might not be the sole cause."
🤖 AI Analysis
"Router placement can impact Wi-Fi signal strength and stability, which could contribute to intermittent performance. However, since the problem affects all devices and the user didn't mention Wi-Fi specific issues, this is less likely to be the primary cause."
🤖 AI Analysis
"While using wired connections can improve performance for specific devices, the user's problem is network-wide and intermittent. This solution addresses individual device performance rather than the root cause of the overall network instability."
🤖 AI Analysis
"Scheduling large downloads for off-peak hours is a good practice for managing bandwidth, but the user's problem is described as random and affecting web page loading and downloads failing, not just large transfers. This solution is more about optimization than fixing a core issue."
🤖 AI Analysis
"Identifying bandwidth hogs is important for network management, but the user's description of 'all over the place' performance and failing downloads suggests a more fundamental issue than just one device consuming too much bandwidth. This would be a secondary step if other causes are ruled out."
... internet speed leaves me hanging intermittently between screens in Safari, sometimes indefinitely. When I remove the USB cable, normal speeds resume.
Jan 8, 2024 ... I pay for 1200 Mbps Internet. Since signing up, I've had intermittent speed issues where on average it drops to 500ish Mbps, ...
Dec 16, 2025 ... Your slow internet speeds are probably caused by very common network issues. You can fix most of these issues yourself; some only take a few minutes.
