Ok, if the LED remains solid white when you have issues, and you lose internet access on both wired and wireless devices, then it is quite likely you are suffering from a known issue with firmware SG4K10002816t that can cause DNS resolution failures with the router, a reboot of the router will temporarily fix it, but the issue will then randomly come back again. A factory reset is unlikely to help.
There is a new version of firmware being rolled out that fixes this issue, but the rollout is happening quite slowly as some other issues are being investigated.
The staff here will be able to help when they pick this post up tomorrow, they may suggest that they send you a router of a different type (the Huawei hub).
Alternatively, if you are comfortable with logging into the router and changing a setting then you may well be able to stop the issue from happening, but it is only a good idea to try this if you have a fairly simple home setup (i.e. just devices that need to access the internet), if you have devices that need to talk to each other and rely on your router to provide local DNS for the devices to find each other, then trying this workaround is probably not appropriate, as it may stop those devices from being able to see each other.
If you did want to try changing settings on your router then let me know and I'll post the details, you can easily undo the change if necessary. But don't worry if you are not comfortable changing settings, the staff here may be able to offer a replacement Huawei hub if they think this is necessary.
