    Archer C2600 Wifi Connection issues

    Model :

    Hardware Version :

    Firmware Version :

    ISP : [/COLOR]

    Model : Archer C2600

    Hardware Version : Archer C2600 1.0 (1.1)

    Firmware Version : 1.1.7 Archer C2600(UN)_V1_160902

    ISP: FROM ROMANIA http://www.rcs-rds.ro Digi Net Fiberlink 1000

    Internet Conection PPPoE
    The issues happen even if IPV6 is ON or OFF.

    I just bought this router. I upgraded the firmware and it all looked good, devices connect to the wifi but they lose the connection with the router or the internet speed drops to 0 after a few minutes, i must admit, the signal is strong but the speed in 2.4Ghz band is very poor (it is between 50mbps and 0).

    The 5GHz band is fine, LAN speed is 936 Mbps, which is fine.
    When I stream a movie to TV, the connection is lost after a few minutes and from TV I can't see the network. SmartShare software from LG does not see the network after several minutes. All these happen in the 2.4 and 5GHz band on WIFI.
    When I connect the TV to the router on LAN port 4, the streaming via SmartShare is fine. These issues are only on WIFI.
    I have attached some screenshots with my settings and speed Lan, distance between me and the router is 1 meter, it is placed on the wall in the middle of the room!!
    Please simulate my problem on the router C2600, having connected more devices,and check the band 2.4 & 5 Ghz with a strong stream Tv!
    IPV6 dual stack works fine on this firmware version Archer C2600(UN)_V1_160902!


    Thank you!

    I truly belive more and more that all Archer router's are **ked up, (not good at all) because the firmware that are released from developers are not good at all.

    Everybody with these Archer c7 c8 c9 c2 etc, seem to have the same issue for few years now.
    And the support don't lissten and don't care

    I tried to do a downgrade to version Archer C2600_V1_150924 , problems persist but It seems to be a little more stable on band 2.4GHz, powe signal & speed in 2.4Ghz band is very poor !
    I know how work the old router wdr3600 in band 2.4Ghz.....!

    Hello, try channel width. 40 and channel 6 or 11 in 2.4 ghz

  5. #5
    I tried all options,versions, this problem persists!

  6. #6
    Also try only N, and wps off on 2.4

  7. #7
    The router that works with the latest recent firmware
    In security, enable WPA2-PSK and AES in 2.4 and 5 GHz, check if your devices support 72 Mbps or 150 Mbps in connection speed with WiFi Analyzer.

    The problem is that i get disconnections on tv and phone, when I am connected to Wi-Fi!
    My phone is a S4, it is able to use this router! http://wifinigel.blogspot.ro/2013/05...abilities.html

    For streaming i use Plex on my notebook. For the wireless settings I use.
    2.4GHZ
    Security WPA/WPA2 Personal
    Version WPA2-PSK
    Encryption AES
    Mode 802.11n only
    Channel Width 40 mhz
    Channel 11

    5GHZ
    Security WPA/WPA2 Personal
    Version WPA2-PSK
    Encryption AES
    Mode 802.11n/ac mixed
    Channel Width 80mhz
    Channel 161

    Dont use notthing in auto, is unstable.

    I tried, the router may have a soft bag or hardware problems!

    I think i know the issue know about Archer Router's disconnect all the time.

    It is because of the Address Lease Time in DHCP, but even if one change to max which is: 2880 it will not help much, because it will disconnect again, but not so manny times. So this is something developer of Archer Router's must fix, (ASAP)

    As your WiFi analysis shows, there are neighboring radios occupying the first 6 WiFi channels. There is even a strong radio ("Tenda_03A388") on the same channel as your family network (channel 6). Thus, the AirTIme available to you and your neighbor is divided between each and every sender using this channel, leaving just a small amount of time for every sending device.

    54 Mbit/s wifi speed means your client uses 802.11g. This mode and speed is negotiated dynamically between the device and the AP according to environmental characteristics such as walls in between the link, interferences such as reflections from steel and walls, distance to the AP, etc.

    To improve your router's WiFi settings:

    Try to use a free (or almost free) channel; this is channel 9 according to your WiFi analyzer. Always use a fixed channel width of 20 MHz. Since each WiFi channel in the 2.4 GHz band spans 5 MHz in width, setting a fixed width of 20 MHz requires as much as 4 channels simultaneously in this band (e.g. channels 7 to 11 if you set it to channel 9).

    All 13 available channels are overlapping, so you will hardly find a completely free channel in 2.4 Ghz band nowadays. Anyway, channel 6 is a very bad choice at your place, since there are already two strong senders occupying this channel. Note that only one device - be it your AP, a client device, a neighbor's AP or a neighbor's device - can use the WiFi channel at the same time, so you share the AirTime with the two other wireless networks on channel 6, which greatly reduces maximum throughput theoretically possible with the C2600.

    If you are sure your client devices support 802.11n, set fixed 802.11n mode. This uses an improved modulation/coding mechanism. If any client device requires 802.11g, it will be limited to 54 Mbit/s wireless speed in this mode. Only n mode will give you up to 150 to 200 Mbit/s WiFi speed, but only at 40 MHz channel width. The maximum of 800 Mbit/s WiFi speed would need 40 MHz channel width, which would require as many as 8 channels to be used simultaneously in the 2.4 GHz band, and 4 spatial streams to 4 separate client devices each transferring at full 200 Mbit/s wireless speed in MU-MIMO mode. You will never ever reach 800 Mbit/s with only one client device in the 2.4 GHz band.

    If you set fixed 40 MHz channel width and n mode only the device will disconnect the WiFi link if it can't allocate the 8 channels needed for this bandwidth in the 2.4 GHz band at any time after going down in speed until the lower limit to ensure a stable connection in this mode.

    Be aware that wireless speed is not data speed. In g mode (max. 54 Mbit/s wireless speed), data speed is about 50% of the wireless speed due to the protocol overhead, resulting in 25 to 20 Mbit/s data speed in real life. The data speed is the speed you measure with web-based speed tests.

    In n mode you can theoretically get much faster WiFi speeds, but only if the 2.4 GHz band is almost free for use with 40 MHz channel width. Also, if there are obstacles between your device and the AP (such as walls) or interferences (caused by reflections or Bluetooth devices) the WiFi devices will dynamically negotiate lower speeds in order to keep a stable connection (this is what you see when devices change speeds, they constantly negotiate the current WiFi speed according to the actual data traffic: if they are almost idle, WiFi speed goes down, but if data is being sent, WiFi speed increases again.

    This being said, getting 40 Mbit/s data speed according to your speed test means that in n mode @ 20 MHz channel width your devices negotiated MCS12, which is 86.7 Mbit/s wireless speed. MCS12 is pretty good in a slightly overcrowded 2.4 GHz band such as shown by your WiFi analyzer. The measures mentioned above for improving the settings can probably increase this speed somewhat, but it all depends on many factors and especially on available AirTime.

    So if you get pretty good throughput when using the 5 GHz band (which according to your WiFi analyzer is almost unused at your place and which has no overlapping channels and thus can grant you full AirTime exclusively even in ac mode with 80 MHz channel width), consider to use only the 5 GHz frequency band for devices requiring high speeds.

    BTW: For stationary devices like a Smart TV I would use a cable connection if it has an Ethernet port. Unless you take your TV with you when leaving the room, there is no real need to feed it wirelessly IMHO, especially not over the 2.4 GHz band.

    Not really. One stream maxes out at 433 Mbit/s wireless speed, so the values reported by the speed test are pretty good for data speed, although somewhat unprecise because of buffering effects.

    See http://www.tp-link.com/us/products/d...her-C2600.html for the specs and http://www.tp-link.com/common/promo/...O/MU-MIMO.html for MIMO speeds.

    Yes really. Sorry to say but you dont seem to have much knowledge about Archer Router's what i've read here in this forum.And one stream NOT max 433 Mbit/s wireless. For the test speed it is a bug in the most Archer router's and the R&C has confirmed this by themselves and they are working on a new update firmware.

    I hate to say this but don't post when you are not 100% sure, nor you are an expert at Archer router's, because people buy this router and think everything is OK, which is not, and it's not free, it coast money.Please don't guess the fixing solution next time, if you don't know 100% maybe it's better not to post.
