Title: DIR-885L Internet Speed is slower after setup
Post by: louij2 on December 22, 2017, 08:27:48 AM
Hi my internet speed is much slower than my older Apple Airport Extreme? Running Google DNS.
The results are the same on Wi-Fi and Gigabit Ethernet

You can see it goes from over 200Mbps and drops on 22/12/17 where I installed the new router.

What FW version do you have loaded currently?

What region are you located?

What is the Mfr and model# of the ISP Modem?

Is QoS enabed on the DIR router?

It is also not auto assigning IP addresses to some devices?

Is your Virgin ISP modem in router mode or bridged? If in router mode, your in a double NAT condition. Try to bridge the modem or if you can't, use the DMZ on the modem/router for the IP address that it gives the DIR router.

Disable all wireless on the ISP modem/router as well.

It is a router in "Modem mode", so it is not giving off any wireless network. I'd have to connect to the modem with ethernet to change anything. I'm using DHCP so it should just work?

I've also gotten a new Public IP after changing the router to the DIR one

My new router also decided to turn off the 5Ghz network for some off reason at around 1am

Is IPv6 set for Local Only on the DIR router?
Title: Re: DIR-885L Internet Speed is slower after setup
Post by: louij2 on December 25, 2017, 03:32:03 AM
Hi it was on auto, set it to local and still getting slow internet.
I even plugged in my old Apple Airport Extreme into one of the available gigabit ports and made a different network and I am getting much faster speeds on the Apple router, when the routers are sat right next to each other now.

Lets try this, download same or prior version of FW to your PC.
Review this and send the FW .bin file to the router using the Recovery Mode:
Emergency Recovery Mode (http://forums.dlink.com/index.php?topic=44909.msg163599#msg163599)

Set up the router from scratch. Set IPv6 to Local only and try setting QoS to your ISP speeds UP and Down.

Should I just not do a normal factory reset first? Also I had the issues with previous firmwares and thought if I upgrade it will fix that but it did not.

Hi it just fails to upgrade everytime I attempt the emergency FW upload, I also attempted a factory reset and changed all the settings and it did not fix anything

What browser are you using? Use IE11 or FF when trying the Recovery mode process.
Title: Re: DIR-885L Internet Speed is slower after setup
Post by: louij2 on December 26, 2017, 11:15:26 AM
Firefox Quantum on my Macbook

Do I need to flash the firmware that it is on or downgrade to the first one?
Title: Re: DIR-885L Internet Speed is slower after setup
Post by: FurryNutz on December 26, 2017, 11:17:02 AM
I would try same version as you have on now.

Try Safari on OSX for recovery mode. Then try FF ESR...
Title: Re: DIR-885L Internet Speed is slower after setup
Post by: louij2 on December 26, 2017, 02:49:23 PM
Tried both Safari and an Older version of Firefox and it failed both times :/

I recommend that you phone contact your regional D-Link support office and ask for help and information regarding this. We find that phone contact has better immediate results over using email. USA has 24/7 online chat. I'd ask about RMA options.
Let us know how it goes please.

I purchased the router through eBay though, will I still be able to get an RMA?
Title: Re: DIR-885L Internet Speed is slower after setup
Post by: FurryNutz on December 27, 2017, 11:44:06 AM
I don't know. I presume if the router was 2nd hand, maybe not covered.  :-\

Call and find out what D-Link says.

They can't help  :'(
Not a problem though

Post by: FurryNutz on December 27, 2017, 02:21:15 PM
Can try returning it to PoP on ebay...

Sorry this didn't work out... :-\

Seller said no returns,
Im not sure if he can do that I read up that he can't, but maybe I'm wrong.
Title: Re: DIR-885L Internet Speed is slower after setup
Post by: FurryNutz on December 27, 2017, 02:35:41 PM
Was there anything in the auction about returns?
