We recently got BT infinity in our area, all devices in the home are able to connect to the hub 5 by wifi but a Dell Inspirion laptop does not get a download speed of more than 2MB and upload of .5mb despite the mac in the same office getting 60MB and 15MB respectively. It appears to be connected and web pages load very slowly but we just dont know what the problem is. I cannot connect it by cable in this room as broadband is elsewhere in the house, the signal has full strength. the laptop is running windows 7. Anyone offer any suggestions?
What connection speed does the Dell quote, and does the HH5 say the Dell is connected at?
It might help to install a wifi analyzer such as Acrylic free https://www.acrylicwifi.com/en/wlan-software/wlan-scanner-acrylic-wifi-free/ or inSSIDer (older version is free). That may give an indication of why the Dell isn't behaving well.
Could be the Mac is using 5GHz band and the Dell doesn't have that capability, and that you are on an unsuitable channel on 2.4GHz
Connect by cable to the Homehub in order to test if there is a problem with the laptop. See what speeds you get when you do that. Also run a wireless speed test when beside the Homehub to see what speeds you get.
If the speeds are OK when you do that it may be the case that you will have to get Wifi extenders.
If having done those tests and the speeds are still bad it has nothing to do with the laptops location and you should make sure that your Network card drivers are up to date. Use the card manufacturer's website to check your cards driver series etc and not Windows which can be out of date.
Yes, in addition to those steps mentioned, have you searched for updates using the inbuilt Dell support app?
On older Dell inspirons, there were frequent driver updates, including the wireless adaptor drivers.
Sorry for the double post which repeats GG suggestions.
Earlier Inspirons had frequent updates, but would not accept suppliers updates.
If you have access to a USB wireless adaptor, try that.
