Model: Archer C9
Hardware Version: V3
Firmware Version: 1.3.1 Build 20171215 rel.35219(5553)

I purchased this TP-Link AC1900 router to replace an old Linksys unit that failed and since installing it I have had really unreliable download/upload speeds on my Xbox 360 and it is affecting being able to play games or streaming.

 

The AC1900 sits behind an Actiontec M1424WR FiOS wireless router the connects to the Internet. By default I have the wireles on the M1424WR disabled. If I enable it and connect the Xbox 360 to it I get an average download/upload of about 20Mbps. This speed is the same whether I turn off wireless on the AC1900 or not. If I connect to the AC1900 the upload drops to 9Mbps and the download drops to 3 - 3.2Mbps. I've tried changing channels, channel width and switching the 2.4GHz mode to G/N or N only. I've tried setting manual DNS but that didn't make a difference. Disabling WMM doesn't either. It doesn't matter if there are other wireless devices connected to the AC1900 at the same time or not but the other wireless devices all come back with wireless speeds averaging around 75Mbps up/dn which is what I'm paying for.

 

Is there something inherent in this routers firmware that is capping traffic to my Xbox or is there a setting I'm overlooking? I searched the forums and didn't find anything specific so if this issue has already been addressed I apologize for the repost.

So for anyone who might still be watching, or happens upon this thread researching a similar issue, the result of all this turned out to be the router failing. After basically being told by support, "sorry, we can't help you. Use a cable instead!" the WAN port on the C9 went kaput and the router is being replaced. We'll see what happens when the replacement arrives but if results are the same I'm going out a buying another router. Overall, I've found the Archer C9 to be a bit underwhelming in terms of overall performance and flexibility. It's Wi-Fi bands are supposed to be stronger than my CPE, but when placed side by side the CPE's range covers almost my entire property( ~.333 acre) and the C9 barely covers the whole house (~1400 sqft more or less in the middle of the property). That's for both the 2.4GHz and 5GHz bands. Using the router as cloud storage was frustratingly slow but I only had an older USB2.0 thumb drive to test with so it may not have been the routers fault. I still think it may bog down trying to manage large file transfers regardless of storage media quality though, just speculation. The printer server feature is flashy but isn't really a printer server. You still have to install an app on your PC that has to be running to print. Why? Let the router's firmware handle that. All of my wired connections performed well both online and over the LAN but that wasn't why I chose this router, wireless was. I hope the replacement changes my mind otherwise the C9 is going on eBay and I'm finding another router vendor.

If you were to wire your Xbox to the TP-Link router, what speeds do you get?

Sorry to the late reply. Guess my alerts don't work. Here are the results of my tests:

 

Wired:

 

Wireless:

 

As you can see, the upload speeds are nearly the same but there is a wicked disparity between download speeds. If you suspect the Wifi adapter is failing, it isn't. If I re-enable the wireless on my CPE and connect through it the download speeds look like those when wired. It's like the Archer C9 is throttling it back.

There is one other setting you could try, that is NAT Boost which is located at Advanced > System Tools > System Parameters, scroll down.

 

If that does not yield any results, I would suggest contacting our support as they will be able to research your case further.

Thanks, Tony but it didn't make a difference. I'll open a ticket with support. Thanks,

First thing we would want to check is the AC1900 in AP mode or is it routing?  2nd when you connect via Ethernet is it to the AC1900 or to the Actiontec?  We would want to rule out any double NAT or any communication issues between network devices.  Another thing we can try is set you MTU of the Xbox to 1472. 

 

 

Best Regards

I'm assuming you want me to change the MTU value on my router because there isn't a way to change it on the Xbox 360 that I know of. It is not in AP mode. Devices on the network only connect to the AC1900. It in turn connects to the Actiontec which is connected to the Internet. The TP-Link acts as a DHCP server, print server and secondary firewall for the LAN which is on a different subnet than WAN facing side of the AC1900.

 

Chaning the MTU size from the default 1500 to 1472 as you suggested had no effect on the download speed. I compared it to the MTU setting on the Actiontec and confirmed that it is also set to 1500 so MTU isn't the cause here. NO, this router is bottlenecking traffic from the Xbox 360 and I want it fixed. I'd like to know why as well but I'll settle for it being fixed. I've opened a ticket with support but apprently everyone is on holiday until the fourth. Guess I'll just have to wait...
