I know you're going to say it's Microsoft's fault, but if you look online most of the people complaining about slow wireless with the surface pro are actually using DD-WRT.

Anyone figured out a work around for how to get the surface pro to be fast on the network?

Thanks!

I noticed this too on the Microsoft Surface Pro. I was only getting 2.5mbit down from Speedtest.net, but was able to use my full upload speed of 10mbit up.

Looking on the dd-wrt wireless status page, the TX was pegged at 5M while RX being 130M for my Surface Pro device. The only way I was able to increase it was to set Wireless Network Mode to G-only. Then both TX and RX were 54M and I was able to use my internet connection to the full extent..

I've heard some luck switching to Tomato, but haven't tried this myself yet. I also wasn't having this behavior on stock firmware (Using Cisco Valet M20 dd-wrt.v24-22118_NEWD-2_K2.6_std_nokaid_small same for 21061).

I'm also seeing this behavior on both bands of my Netgear WNDR3400 (rev1.)
I get about 400 kBps down, but much faster up. I get 2-4 MBps down on another (non WRT) n-lite router I'm using as an AP.
Oddly, the low download speeds on the 2.4GHz band are both on my local network and Internet, whereas on the 5GHz band, I can about saturate my cable modem on downloads, (over 4MBps. 37Mbps on speedtest,) but accessing stuff on my local network I'm limited to the 400ish kBps.
Other devices (like my phone) have more consistent performance.
I don't know what my bandwidth was before flashing WRT, but it was significantly faster.

Oh, and I've messed with security settings, N only, G only, A only, etc, nothing really had an effect.

I can confirm this.

Surface and a Surface Pro 2 both have dramatically decreased download speed compared to other devices on the network.

this is true for two different networks with a E2500 and E4200, respectively both running Fractal's 23040.

I've tried any number of different settings. Any ideas?

I'm using a Surface Pro (1st gen) and my dd-wrt page is showing 135M TX rate and 270M RX rate.

I'm connected on 5GHz (set to N-only) on a Linksys e4200(v1) with build 23320 K3.0 mega. I'm also completely up-to-date on the Surface firmware updates from Microsoft (they often include Wi-Fi fixes in there).

Hope this info helps anyone diagnose their problems!

Add my vote to this. I've experienced this on my Dell Venue 8 Pro which is a Windows 8.1 tablet. Here's a repeat of what I wrote on another forum:

Source: http://forum.tabletpcreview.com/dell/62086-dell-venue-pro-8-slow-download-fast-upload-via-wifi.html

I have a 50 megabits down / 10 megabits up Internet connection.

I noticed my download speed being abysmal so I ran a speed test I'm consistently getting 1.5-2.5 megabits down but getting my full 10-11 megabits upload speed (via Speedtest.net). I get a consistent 57 megabits down when using my wired desktop connection.

These are the following things I've tried:

1.) Disabling WMM on my Asus RT-N16 router running DD-WRT (half a megabit improvement)
2.) Resetting TCP/IP via netsh (no improvement)
3.) Reset TCP/IP Autotunning, as described here (no improvement): http://fixedbyvonnie.com/2013/10/how-to-fix-limited-or-no-connectivity-wi-fi-issues-in-windows-8/#.U1BJBvldXhJ
4.) Set my Wifi 2.4ghz Channel Width to 40mhz (this doubled my download speed to an average of 5 megabits but still a fraction of what it should be, and I don't like running at 40mhz channel width since the speeds tends to fluctuate a lot more when using with my laptop)
5.) Revert to earlier Wifi driver (no improvement, currently running the latest from Dell)
6.) Connecting to a neighbor's open Netgear Router Wifi running stock firmware (1 megabit improvement).

As a secondary issue I have an Airlink 101 802.11g router running stock firmware configured as a regular access point but trying to connect to that I only get either limited connectivity on the Venue Pro (access to local resources, but not internet), or sometimes full connectivity but still no Internet access.

No other computer/laptop/netbook/tablet/phone/tv/etc.. in my household exhibits these problems.

But when I connected to a Netgear router running stock firmware I saw no real improvement.

Well I took a 3rd router I had laying around, an identical one to my main router, an Asus RT-N16 and I flashed that to Asuswrt-Merlin, which is based on the stock firmware. I configured it to AP only mode and when I connect to that access point my downloads are from 40-50+ megabits, where they should be. So it sounds like the WiFi built into the Venue Pro 8 has a bunch of compatibility issues with DD-WRT and some older router models, hopefully these can be resolved via updates from Dell/Microsoft/Intel.

Update: A friend of mine with an Atheros (mine is Broadcom) based DD-WRT router doesn't have these issues with his Dell Venue 8 Pro.

Update 2: Another possible work-around is to set the router to B/G (though you lose N speed, source: http://slickdeals.net/forums/showpost.php?p=67542930&postcount=901)

Same issues the others are reporting.

Surface Pro 2

Office with e3000 + DDWRT

Home with e4200 + DDWRT

5 Megabit max down... sending no problem.

Just wanted to +vote this if anyone has a solution. What is strange is, my Galaxy S4 when my surface pro 2 is on, also gets horrible down. Very strange.

[DutchmanIII]

well, after playing with all the settings and combinations I finally gave up and flashed AdvancedTomato.

although it hurt me a bit to abandon dd-wrt, i do enjoy the full bandwidth on my surface.

I've made the change on my E4200v1. Havent tried on my E2500 or RE1000 yet.


Edit: firmware issue has been fixed in latest release

[BrainiakZ]

Struggling considering moving to AdvancedTomato... I like DD-WRT so much. How do you like it since the move? Maybe I will do the same thing.

[RedRover]

I also am noticing this frustrating speed limitation to ~5mbps down with the Surface 2. I run the latest Standard Kong on my E1200 Linksys/Cisco. WPA2, AES only, OpenDNS, N/G network.

Any solutions? Considering Tomato or returning to stock.

Has anyone tried the Comcast fix?

http://www.dd-wrt.com/wiki/index.php/Comcast_download_speed_fix_for_Linksys_eSeries

I never used to have any problem with any devices and do not even subscribe to Comcast. However, when I bought it, my LG G2 had awful wireless speeds that were remedied by this fix.

My main gateway is the E3000 router and it has K26 KONGVPN version 22000++ and when I run the command...
iptables -t mangle -L -v -n

I have one for DSCP listed (with no script commands added)...

Chain POSTROUTING (policy ACCEPT 305K packets, 278M bytes)
pkts bytes target prot opt in out source destination
3204 2147K DSCP 0 -- * * 0.0.0.0/0 0.0.0.0/0 DSCP match !0x00 DSCP set 0x00

Which tells me that DD-WRT is automatically making the correct changes to DSCP on the outbound wan. To make changes to the inbound wan I added this firewall script...

iptables -t mangle -A PREROUTING -i `nvram get wan_ifname` -j DSCP --set-dscp 0

Now I have DSCP setup to zero on both inbound (PreRouting) and outbound (PostRouting) WAN packets....

Chain PREROUTING (policy ACCEPT 215K packets, 191M bytes)
pkts bytes target prot opt in out source destination
137K 175M DSCP 0 -- vlan2 * 0.0.0.0/0 0.0.0.0/0 DSCP set 0x00

Chain POSTROUTING (policy ACCEPT 212K packets, 194M bytes)
205 19013 DSCP 0 -- * * 0.0.0.0/0 0.0.0.0/0 DSCP match !0x00 DSCP set 0x00

Hi All,

The issue is with DDWRT and the wireless adapter on the tablet/computer. Most likely Broadcom chipset routers. if i flash my router with stock firmware wireless is fine.

A quick fix/workaround is to set your router (ddwrt) to b/g only on the 2.4 GHz or flash to stock firmware.

I have the same issue but with a dell venue 8 pro. Patiently awaiting for a fix. I'm using a pocket size tp-link as an AP in the meanwhile.

I hope this help someone and arise the attention of one of the developers, to see if it can be fixed.

I managed to get higher download speeds by changing the "MIMO - Transmission Fixed Rate" to 15-270.


Needs further testing, however.
