need some help from experts here regarding router setting...
my setup : - BTU : Alcatel Lucent I240G - Router : Dlink DIR-842 (NEW) - Cable : CAT 6 - On Unifi 500Mbps i follow the setup wizard in the dlink router to setup my unifi for both 2.4Ghz and 5Ghz... i use my phone to connect to 5Ghz wifi and speedtest can reach around 200mbps, which is ok for me...then i use my laptop to connect to the 2.4Ghz wifi (my laptop does not support 802.11ac), the speedtest result is disappointing in which the result only give me 25mbps for both download and upload speed... sad.gif before this i only use my old router which is the TP Link TL-WR841HP Wireless N router, and my laptop (connect to 2.4Ghz wifi) can get constantly good speed at around 75 to 80mbps for both download and upload speed, upon change to the dlink dir-842, the speed drops a lot and never can exceed 30mbps... sad.gif have i done something wrong on the dlink 842 router setting? or i need to do extra setting for the 2.4Ghz wifi? really appreciate some help here...thx a lot... smile.gif |

QUOTE(StuartLee2015 @ Sep 25 2018, 11:38 PM) I got the same setup as yours, just with Cat5e between router and modem... i actually do have and TP Link AC adapter, but the adapter wont recognised by my windows 8.1 laptop so cannot use that adapter (i m sure the AC adapter is working fine as i tested it on my brother's laptop which is running on windows 8.1 too)...so i have no choice but to use my laptop's built in wifi... Get yourself an AC adapter.. i not sure why 2.4Ghz speeds drop that way . Previously on 50Mbps plan, i was using RT-N12HP_B1, and DWA131 N300 wifi adapter. I can constantly get 45 to 51 Mbps.. right after I got Turbo-ed , I was baffled on the 2.4Ghz speeds from 0.13 MBps to 20Mbps .... as for asking why here, all suggest to change the router, which i will eventually do anyway.. but i just want to know why only. So I then made a report to TM and they come and just changed the Router and my j7 Pro Samsung which have AC, can hit at least 200Mbps now.  i just do not understand why on wireless N router 2.4Ghz speed is constantly good, while on the DIR 842 the 2.4GHz speed is terrible...  |

QUOTE(StuartLee2015 @ Sep 25 2018, 11:48 PM) yea, maybe try another AC adapter? D-link installation method is really tricky... I not sure whether it's the same for ASUS, TP-link, etc... Fixing the my Wifi adapter infinity on/off took me a week , as asking here won't help much , so i just experiment it on my own. As of now i dun hv other AC adapter, but i try to plug in my old tplink wireless N adapter to my laptop just now, it is being recognised n wirks smoothly...just that AC adapter wont work on my laptop, but can be use on other laptop n pc without problem... |

QUOTE(SilentVampire @ Sep 25 2018, 11:57 PM) Probably your old router has better 2.4GHz coverage, with better antennae and high gain ones. Try using a WiFi analyzer and go on the least congested channels, and see if that improved things. Another thing you could do is to switch to a better router. I just bought that dlink router from someone (btw its the dlink router provided by TM), so wont be changing the router so soon...As for your AC adapter not working on your Windows 8.1 laptop, upgrade to Windows 10, or just go to TP-Link website to manually download the driver for the adapter. It will work then. As for the AC adapter, i already try manually download the driver n install it, but my laptop just wont recognised the adapter... |

QUOTE(JohnLai @ Sep 26 2018, 12:35 AM) In a sense....if you really need to use 2.4ghz....why not plug a LAN cable from DIR842 to WR841HP? (Make sure DHCP Server is disabled at WR841HP and turn off DIR842 2.4ghz) can it be done like that? i never try this before...  |

QUOTE(JohnLai @ Sep 26 2018, 12:53 AM) Of course can. ok, will try that tomolo...thx again for the info... Second, plug a cable from your DIR842 port 2 to WR841HP port 1. Don't plug into the WR841HP WAN port. Just follow the guide here https://www.tp-link.com/ae/faq-1933.html |

Is there something wrong with my unifi connection?
I m on unifi turbo 500mbps package, using Dlink DIR -842 router by tm... I tested the wifi speed on both my Huawei Honor 10 and Asus Zenfone 5 smartphone, max can only reach around 180mbps... I test it with my laptop using tplink t4u wifi adapter, max speed also around 190mbps... I thought its normal for this speed since wifi on the DIR-842 can reach max around 300mbps... But today when i tested it with my newly bought Xiaomi Mi Pad 4, i m surprise to see that the speedtest can reach 470mbps on wifi...  Something wrong with my mi pad 4 or the Dlink router? and i always thought Huawei device network connection is always better than xiaomi device... FYI, i tested the speed on both Ookla Speedtest app and the Unifi speedtest site, both show almost the same result... Attached thumbnail(s)

Not sure whether this has been posted b4 or not, but looks like its much more difficult and not convenient for unifi termination now...
