Hello!

I have a WHR-300HP Buffalo Router that has used DD-WRT for years.

I just moved from West Coast Comcast to Chicago Comcast. When I use the buffalo router here the Wifi is really slow, and it was not in Cali. I am currently using the rented equipment and want to buy my own modem, so making sure the router wont be my weak point.

My concern is that here when I plug my Buffalo Router into the Comcast modem/router combo the WiFi sucks.

Speeds:
Comcast WiFi: 80 Mbps
Comcast hardwire: 90 Mbps
Buffalo DDWRT hardwire: 90 Mbps
Buffalo Wifi: 20 Mbps

I tried putting what is listed as the newest firmware on it (but it seems pretty old) : DD-WRT v24-sp2 (03/25/13) std

I have tried changing the Network Mode to N only, and the Width to Turbo 40 Mhz. QoS is not activated. That is basically the extent of my knowledge.

I am asking: can anyone recognize the problem, recommend a next step for troubleshooting, or perhaps just tell me that it is old and I should buy a new router or something.

Please let me know what further details I can provide.

Thanks!

Since you posted in this forum, I'll assume you meant you have a whr-300hp2.
The newest firmware is from 2 days ago. ftp://ftp.dd-wrt.com/betas/2016/11-14-2016-r30880/buffalo_whr_300hp2/

I don't know if that would fix your problem or if that firmware won't brick your unit but it is the latest.
Also chances are that setting the channel at 40mhz might cause interference with those around you.
On the crowded 2.4ghz band, it's best to use 2mhz and the least used of ch 1, 6 or 11.

Yes, wrong forum. Your router is an atheros unit. I will move it to the correct forum.

Might want to read this thread http://www.dd-wrt.com/phpBB2/viewtopic.php?p=958010

Maybe your Comcast AP and Buffalo AP are using the same channel. Run a site survey on the Status->Wireless page to make sure you're using the least congested channel, either 1, 6, or 11.

You cant be serious, surely?

A router's wifi doesnt care about what ISP it is, only about what technology is supported by its hardware and by the device that connects to that AP supports in terms of that wifi tech.

Also WIFI speed and distance are relative and both very dependent on environmental factors that may cause interference and reduce one of those or both. So, your house in postcode A, its build materials, and other radio interference from many sources of EM generating equipment (or even radio signals/frequency/channels generated by your or your neighbors own equipment) that these use vs House in postcode B and its build materials and other radio interference etc. (put is simple terms)

So now you know more or less the crude basics of radio signals, you can find out the reasons for yourself to the questions you ask by applying some of that scientific method of investigation and common sense.
