Hey Guys,
Been using DD-WRT with a D-Link DIR-615 D4 for about three months now. The connection is rock solid no dropouts or connection issues of any kind however the performance is all over the place and fed up of having to constantly mess around with settings.
The problem is I am in a large house with around nine people each with laptops, tablets and phones all using this one connection. The ceilings are high and walls thick, router is in center of the house on second floor.
Most common use is: Streaming (movies, tv, youtube) Skype, Gaming and general Browsing. I am not sure if people are torrenting or file sharing.
We have a VirginMedia (UK) fibre line with around 30Mbps/4Mbps this comes from a SuperHub2 which is in modem mode connected to the DIR-615 D4. Before I used this method we constantly had dropouts on the Superhub2 many times a day resulting in having to flip the fuse box to the main supply to reset since the router is in a guys room who works late.
Monitoring the bandwidth from admin there are constant spikes and then normalization. I have been using a script generator setup as a firewall with limits per mac address from being generous to hard limiting. Currently trying QOS but still no good. I have all the settings based on my knowledge and posts from here to get the maximum out of my setup but I am losing my hair. Gaming is never pleasant with constant lag spikes, trying to watch films have buffer issues.
My chipset is: Qualcomm Atheros AR9485 I bought an Intel 7260 AC but that was unusable, terrible performance. I have 150.0Mbps on the adapter with my current settings. Using the latest Firmware DD-WRT v24-sp2 (03/05/15) std - build 26446 have also tried many previous builds and the original old one from Router Database.
What I am needing is to have the network speed distributed equally between each device for example: 1Mbps for each device.
I have attached screenshots of my current setup, can someone please help me out here to a possible cause or solution please?
Can you please post a dmesg result ? (connect with SSH or Telnet to the router and type dmesg)
Then, try these:
1. Wireless -> Advanced Settings -> CTS Protection Mode: Disable
2. Administration -> Maximum Ports : 8192 (instead of 4096, in case someone does heavy torrenting)
3. Physically set the router's 2 antennas so that they are almost perpendicular to each other (V shape, with 80-90 degrees angle)
4. Install latest drivers for the machines (this IS important)

Just done those changes you suggested and already seems to be better. Although with it being 12.40am I don't think people are doing anything heavy and some people are away for weekend.
Will keep an eye on it but love to have more feedback where there can be.
Still getting random performance it's driving me insane! Not sure what else I can do, I monitor the router 24/7 trying to find a solution, have used every build.
I have tried capping everyone to 800kbps down 10kbps up - each using the firewall scripts leaving plenty of room for me to test things but still getting slow speeds. Did a test last week using the Virgin Media Super Hub 2 (default isp router) and I got full speed 50Mbps/4Mbps.
With the D-Link DIR 615 as router and Super Hub in modem mode I get around 10Mbps/3Mbps.
Received RX has 771 errors after being up 10 hours. TX power is at 50mW. Rate is running at 300 Mb/s, HT40 mode. Using all the settings recommended previous from months back and months of research myself.
Any ideas please, any way to diagnose or export a report for people with knowledge to check?
Supposed to be 50Mbps / 4Mbps yet getting these low results and constant drops/peaks, never consistent rates. If I remove the D-Link router and use the ISP supplied router I get full speed but it keeps dropping hence having to use as modem mode.
OK, let's see. I remember giving you some advice, but can't remember what and how... it was long ago. What build are you using ? _________________ THERE ARE NO STRANGERS HERE; ONLY FRIENDS YOU HAVEN'T YET MET.

Yes I still have the same settings you advised above but still getting poor results. Have been researching and playing around with settings for the past two months, can't get anything to be stable and consistent, having to mess around every day.
Ordering a Cat 5e cable, should solve the problem I would imagine, someone else can deal with the wifi. Not ideal as having to tack 100M cable all over the house.
OK, did you try to disable QoS ?
Also, did you update your Atheros WiFi driver to 10.0.0.308 ? _________________ THERE ARE NO STRANGERS HERE; ONLY FRIENDS YOU HAVEN'T YET MET.

Can I see a snapshot of Setup -> Basic Setup in DD-WRT ?
Also, did you disable CTS Protection Mode, as I said above ? _________________ THERE ARE NO STRANGERS HERE; ONLY FRIENDS YOU HAVEN'T YET MET.
