As mentioned before, use the 5GHz band, and you will get the full speed, and don't bother with Apple AirPort Extreme. Stick with TP-Link if you're on a budget, and go with Asus if you have a higher budget.

Answers:

1) Hard to say without looking at your equipment and settings, but it could be as your brother in law say, too many interference as you're living in a condo and your Wi-Fi 2.4Ghz band is very congested. It can be contributing to your problem as every wireless access point that are sharing that same channel as your router are fighting for frequency space.

2) Before you do anything, download a wifi analyzer app on your phone (Wifi Analyzer by farproc) or computer (Acrylic WiFi) and see how many WiFi channels are being used and how many wireless access points are using that channels. I would not change the router yet, depending on the result, but I would go into your router, and try configuring the 5GHz band to be used, and only use the 5GHz band and it's corresponding channel, for a more stable connection.

Yes, that's one of the problems with Archer C7v2. It's a very stable router but its 5GHz band is very fickle, and unstable at worse. That's why I have disabled the 5GHz band in my router. Ethernet is still the gold standard for a great connection anyway.

D-Link have responded. Don't forget to update your firmware on 21 September to those that have the router:

True. If I have that router, I would NOT use it until I'm 100% sure that the problem is fixed. However, my trust in D-Link routers is very low at the moment as they have had multiple vulnerabilities reported in recent years. I would just use another brand of router instead.

Well, unfortunately, if you are using that particular router, and your current IP address is listed somewhere as having open ports, you are still vulnerable, even if you're on Time.

You could check:

Replace the Xs in this link https://www.shodan.io/host/xxxxxx with your public IP address. A result of "Not Found" is best. If anything is listed as open, I wouldn't worry about it if you have disabled remote management.

I have it enabled but I have changed the default username, default password, and port. It might not be a security measure but it is definitely something at least. If you want to enable it, make sure to do as I mentioned above.

Should be fine to leave it as it is. Just keep monitoring it.

You should have changed it a long time ago. That's the worse router, with multiple vulnerabilities reported that had not been patched. Change it to something decent, like TP-Link or Asus, if you have the budget.

Might be a router issue rather than a connection issue. Have you tried switching to another router?

Chill bro. I'm just suggesting an alternative solution to your problem. I am also on Maxis and so far it's stable for me, so just thought I would give you another choice. If you want to change to Unifi, just do it and it might solve your problems.

Yes, but as prokiller1199 have already mentioned, you will need LAN cable access from your 1st floor to the 2nd floor, and follow the instructions to set up the TP Link Archer C5, as an access point. You can't do it wirelessly.

I'm assuming your D Link cylinder DIR-850L router is provided by TM and you updated the firmware with the Retail firmware update? In that case, you should not have updated the firmware as it might not be suitable for use in your TM-provided router. See here for recovery method to be able to use the router again: https://forum.lowyat.net/topic/3237458/+120

The firmware is broke if you're using the cylinder D Link DIR850L router. If I were you, I would get another router ASAP, something better than the rubbish bin router.

Sounds like you receive the infamous rubbish bin D-Link DIR850L router that have to be updated to the latest firmware as there are multiple vulnerabilities. The TM-specific firmware has just been released today. Update the firmware ASAP if you can. I'm quite surprised they gave you this router, instead of the TP-Link C1200.

I'm currently using the TP Link C3150 that I bought myself but my gf's house is using the TP Link C1200 and it's very stable so far, with the latest firmware and coverage is very good as well.


Wifi coverage is bad and multiple vulnerabilities have been reported so far, so you'll have to update the firmware yourself ASAP as the new firmware for TM has been released. Can't really trust D-Link products anymore as most of their products are full of vulnerabilities, even their premium routers, and I used to be a fan of their products. See here:

Yes, but you'll need to update your firmware ASAP as I mentioned above, and my trust in their products is very low at the moment. See here : https://www.stuff.tv/sg/news/these-d-link-r...vulnerabilities

I know la bro. I'm using that as I have the budget and I want to see if TP Link higher priced router are comparable with Asus higher priced one, and it's actually not too bad. I like it so far. Just get the TP Link C1200 as it's very stable and reliable as I said.

Yes, you can get it from TM but you might have to renew your contract with them, or just say your current router is spoiled lol.

You mean you don't get it? The pricier routers are usually better than the cheaper routers, but not always. They have better features, better reliability, and generally are more nicer to use. As us still leads the way followed by TP-Link, and lastly Tenda. D-Link is at the bottom of the list with their vulnerability issues.

Yes, more features, and better firmware.

2.4Ghz or 5GHz? Could be a congestion/interference issue.

Lol overkill la bro. AC1900 is more than enough or AC3150 v2 from TP-Link is good enough.

If it's LAN cable as well, might be something external and not related to your own setup. Good luck in getting hold of them.
